Wavelab 10 Missing Files window problem

I’ve been experiencing an issue with the ‘Missing Files’ window in Wavelab 10 for several months. If files used in a Montage have been moved/relabelled, the additional ‘Missing Files’ window opens, but I can’t access it. I can see it when I hover my cursor over it, but if I try to click on it/select it, it disappears. At that point, the only way out is to close the program. I use A PC running Windows 10.

I’ve just updated Wavelab 10 to the latest build, but the issue persists. Any clues as to why this is happening?

A screen shot (not a phone picture of your screen) could really help get a better idea of what’s going on.

I don’t know Windows very well so I’m not sure what I’m looking at, but maybe @PG1 has some thoughts.
