I have a problem with the reader continuously jumping to the top or bottom of the page when opening a previously viewed comic. The jump happens every time I try to scroll after reopening a comic and it'll keep doing that for about three minutes or so and then it'll stop and work normally. When it happens if I scroll it'll return to the top of the page a second after I'd begun scrolling. If I scroll up to the previous page it'll do the same but instead it'll continuously jump to the bottom of the page. It only happens for the first three or four minutes of opening a comic that I'd previously opened. Upon first opening a comic it works perfectly fine until I close and reopen it. The issue happens on all forms of scrolling (keyboard, mouse wheel, mouse dragging). It doesn't seem to be related to my mouse or keyboard and I have no such issue in any other program.

I have tried restarting my PC as well as reinstalling YACReader while confirming that the installation folder was deleted from Program Files after uninstalling. I have also tried deleting the YACReader folder from AppData. Unfortunately none of these fixed the problem. My only workaround currently is to simply open a comic and wait the three or four minutes for the problem to stop before I begin reading.

I'm running YACReader version 9.7.1.2009123 (64-bit) on Windows 10 (64-bit). I first downloaded YACReader yesterday so I've had this problem for as long as I've had the application it seems. It's probably not relevant but I installed the program to a separate HDD from my OS' dedicated SSD.

Hmmm, I can't replicate the problem. What fit options are you using?

Hello, firstly, thank you for developing a wonderful comic reader for all of us to enjoy!

Now to my issue: I am also experiencing the bug that OP has described / experienced, of YACReader continuously jumping to the top of page after I have scrolled down the comic.

Like the OP, I do not experience this behavior when first opening a comic but when I re-open a comic from "Continue Reading" within YACReader Library, I have noticed this odd bug occuring.

Regarding my set-up:

I am using Windows 11 OS with the latest updates installed. (Edition: Windows 11 Home, Version: 23H2, OS Build: 22631.3155)

I am using the latest version of YACReader as of 03-08-2024. YACReader-v9.14.2.2402143 for Windows 64bit (with 7zip and rar5 support - Qt6 build)

I am using the latest Nvidia drivers for my GPU. (NVIDIA GeForce RTX 4060 Ti. 8GB -- Version: 551.76 WHQL. Release Date: 2024.3.5)

I am using the "Fit Width" option in YACReader. Not zoomed in.


Any and all help is appreciated, much thanks once again to the development team.

Hello, thank you for the reply and look into this matter!

I have tried to re-open other files from the YACReader Library "Continue Reading" menu, both .CBR and .CBZ and have not encountered the aforementioned scrolling bug. I wonder if the originally affected file itself or perhaps the folder / naming structure could have some affect on replicating this bug?

I have also noticed that setting another "Fit" option such as "Fit Height" or trying another Zoom Level "110% zoom, 120% zoom, etc.) do NOT alleviate the aforementioned scrolling bug, it remains present.

Do you know of any program / app which I could use to view the File Info of .CBR and .CBZ files? I wonder if I could find a difference / discrepancy in encoding options between the affected .CBR, and the non-affected .CBR, .CBZ files which do not replicate the aforementioned scrolling bug.

Once again, much thanks to you.

cbz and cbr files are just zip and rar files respectively, you can use programs like winrar or 7zip to take a look.

Thank you for your reply and your suggestion as to using WinRAR, 7Zip, etc.

I seem to have fixed the scrolling bug.

I opened the affected .CBR in 7Zip and noticed that the image files were in a subfolder, the structure looking like this: CBR File > Folder > Sequential .JPG comic images.

I then opened a non-affected .CBR and .CBZ and noticed that the images files were not in a subfolder, the structure looking like this: CBR File > Sequential .JPG comic images.

So I went back to the original affected .CBR file, extracted the included .JPG images and created a new .ZIP file from them, this time with no subfolder. The structure now mirroring the non-affected .CBR / .CBZ files (CBR File > Sequential .JPG images). After that was completed I then re-named the .ZIP file to .CBR extension and then imported it into YACReader Library.

I opened the newly made .CBR file in YACReader and browsed / scrolled a few pages in, closing YACReader.

I then re-opened the newly made .CBR file from the "Continue Reading" menu within YACReader Library, expecting to replicate the aforementioned scrolling bug but to my surprise it didn't occur this time.

I now consider this issue solved / closed.

I will keep a look out for this scrolling bug occurring in the future and will try to fix the affected file in the same way as listed above if it is encountered again.

Thank you very much for your time and assistance.

If you still have the affected file, please use the contact section in this web to send it to me. The app should not behave differently because of folders inside a comic file.
