Since the last update (5.0.2.2500) I've been getting a lot of crashes during certain right-click operations. I haven't had a chance to find out exactly how to reproduce it yet but it always seems to happen when right clicking on a track and then mousing over the pop-up menu.
Will try to get more detailed info but here's a partial error I managed to screen grab:
When it crashes I have to force quit using task manager and it's happened probably between 10 and 20 times recently.
