Hardware and OS: I am running the 32 bit Windows version of 4.8.1 on Ubuntu 26.04 using bottles.

But I don't think the problem is related to my environment.

When zooming in to the highest zoom level it is not possible to zoom out from there using the mouse wheel.
It does not matter whether the highest zoom level was reached by mouse wheel or the virttual zoom button on the right sight of the window.

Zooming out using the virtual zoom button is working (but you have to find it on the desktop as it is not always shown).

Because the zoom level is saved on application shutdown, restarting the application did not help to fix the situation in this case.

regards

Peter
