Slideshow timer does not allow to close slideshow at the end

[mysterix]

Ver. 0.99.6 Win (10 Pro) x64
When I set timer, the slideshow still shows a picture after time is up. Then if I try to close it by clicking/doubleclicking nothing is going and only "esc" key closing a slideshow (but it should close automatically with timer). Or, maybe I do not understand something... It worked good in Xnview Classic. The bug exists both with starting inside application and from a file.
And another one bug: seems like smoothing algorithm works worse in slideshows at fullscreen mode compared to simple viewing photos — I see stairs if a photo has slightly smaller resolution.

At the moment, I solve the problem of slideshow closing by .SLD file and two batch files:
Batch1:
start timer.bat
Slideshow.sld
exit

Timer.bat (Batch2):
ping -n [Full slideshow time+1 second] 127.0.0.1 > nul
taskkill /f /im xnviewmp.exe /t
exit

Thanks to your detailed description I can reproduce the problem.

do you use display font scaling?
