Doesn't seem to happen all the time, but it happens enough to interfere. When I command "G" and begin to drag the mouse on the graphic's timeline the M100 freezes.
It's also been doing it when I move video tracks from the bin. The mit seems to get a red 'x' indicating an invalid track, but then it will not change and the program freezes up, so, I need to re-boot.
Yes, we have experienced this issue as well. Annoying. Annoying. Annoying.
Our current workaround is to click to the finder, HIDE OTHERS then click back into the Media100 application.
We select an action other than click/drag once we go back into the application (dont try to immediately do the same thing). If it doesn't crash..it usually works for us. If not, at that point we save/quit/restart the application and all is fine.
