XnView Software

The problem persists on the clean Win10 v22H2 virtual machine as well.

I've tried on the clean Windows 8.1 x86 virtual machine: only VMware Tools, MS Visual C++ 2015 Redistributable, XnView 2.51.7 and FinePrint installed. The problem persists.

BTW it is worth to mention in Readme.txt that MS Visual C++ 2015 Redistributable is needed for XnView to work.

I confirm, the issue is still there.

Try to print attached GIF file. It is printed correctly in XnView up to v2.51.1. In newer versions, print looks like attached JPG file (I get it with FinePrint but the issue is present with real printing, too).
Settings reset to default. Win81 x64.

Please add the possibility to modify mouse wheel actions by holding Ctrl, Alt, Shift, Win and its combinations.

Currently, if Auto Image Size is set to No fit XnView centers the image so we're seeing the middle part of a newly open image. Please change this behavior or add an option that would allow to see the upper part of a newly open image.

Sorry the animation seems to be gone because of attaching. http://mir.cr/1VFF7BHQ

Attached file has 3 pages. They're displayed correctly when animation is on but incorrectly by manual page change. WinXP SP3, XnView 2.39.

Log onto system under limited user account.
Run xnview.exe (for the first time under this account) via "Run as" using admin credentials. You'll get the Startup Wizard window.
Press "Run the File association(s) tool". You'll get Run As prompt - which you shouldn't really get 'cause xnview.exe ...

Will Associate tool associate "more than 500 file types" that XnViewMP support? Now the list looks more than modest.
