Hi!
The first picture describes the problem correctly! The reason I added code for the slide sorter view, is that I get the run-time error there too, if the cursor is between two slides.
So I get this run-time error in two occassions. Slide Sorter View is fixed now, but "If the cursor is between two slides in the left-hand pane with slide thumbnails" not...

I was now thinking about something like "If Selection is nothing Then do nothing" Or maybe "Exit Sub" to skip the whole refreshing in that case. But I don't know if that is possible...
