Thanks Michael for the quick reply.
Unfortunately, it has nothing to do with that, but maybe it's a setting in Irfan View.
Should Java Script be installed?

My colleague works with Windows 11.

Hi Franz, do you mean that test shortcut above with a 1000 x 1000 pixel size still doesn't work?

And updating the video driver didn't make any difference either?


re:

MOI has JavaScript built in, it doesn't need to be installed separately.

Hello!

We found the error. It is probably due to the new version of Irfan View.
We have now installed the slightly older version and everything is working again.
“iview452_x64_setup.exe”

Thank you very much,
Franz
