Freeze on Import

I've actually been having a similar, but more sporadic problem with the "Save" function for quite a while now. Then, when I upgraded and got the freeze on import, I though it was more consistent and I could have something solid to report. Turns out it's not consistent, either. Basically, after a while of using screen-scraper, I completely freeze when trying to Save (or now, after Importing from the menu). Oh, and the Save and Import work fine; once I come back the command has completed.

Once the workbench starts freezing, it freezes very consistently, even when I restart it. The only way I can get it to stop (for a while) is by restarting the "screen-scraper server" Windows Service. I'm running on Vista, and it doesn't seem to matter which file I'm saving or importing, although it feels as though it happens more often when I have a lot of scrapes loaded in the workbench. It also seems to happen when I've had the workbench open for a longer period of time. The only other difference in my setup is that I load in a java library I created, in the "ext" folder, which creates some RemoteScrapingSessions. I would test it without the library, but I really need it :)

I'm sorry; I know these bugs are super frustrating, which is why I was trying to wait till I had something more consistent. If there is some way I can turn on logging or output something when the crash happens, I am more than happy to. The freezing doesn't happen often enough to be unusable. And, I'm fairly certain it doesn't happen on the 4.5 stable release, just the alphas.
