This bug has been in Vegas since 11 and still no fix. Happens on all my machines e.g. render, navigate to folder, create new folder, Vegas crash. Not every single time, but most times.
as much as i sympathize with your predicament, i would be looking elsewhere - if the problem you mentioned was really a 'bug' then this, and other forums would be truly lit up....
It's a bug. But once you're aware, it's not a problem, you just don't do that. Still, you'd think it's something that could be easily caught, at least give you a warning message.
It usually happens when drivers are in sleep mode, especially USB drives. On my machine, I turned that feature completely off for all drives. I never had that crash.
Yeah, sorry, I really hate this bug too. I've spent DAYS trying to find and fix it, but have failed so far. Frustratingly, every time I look at it with the debugger, it doesn't happen...
Note that the default Windows (7) High Performance Power Profile allows the hard drives to spin down after 20 minutes. If you haven't altered the profile to Never, they could not be spinning when you attempt to create your folder.
This may be just happenstance, but I only started noticing it after I installed Vegasaur, as well as an innocuous bug that causes Vegas to create a windows error after I close it "Vegas has stopped responding... etc"
