I love Irfanview because it can make a slideshow of both stills and video's. Of course, getting the video option to work sometimes requires some doing, but now I suddenly have an odd problem: a message box pops up, telling me Irfanview can not show the video. Meanwhile, even behind the box, the video starts playing! Nothing wrong with the sound either. So it's just this error messagebox which is bugging me, but I can't find a way to disable it.
This happened on the 64-bit version (on Win10), so I completely de-installed that and downloaded the latest 32-bit version. Same message. The video's are of type .3gp and mp4. Any suggestions would be appreciated.
