I was messing with the viewing options of the "Open" window, then I opened, and... crash.

I'll need some better repro steps than just "I was messing around" ...

[trickman]

Well, actually I don't remember... I just... messed with it

[Rick Brewster]

I get crash reports like this every once inawhile through paint.net@hotmail.com ... and I can never tell what's at fault. Is it my code? Is it Windows' code? Is the system just overheating or overclocked or has bad memory and freaking out?

So if you ever find a solid, consistent set of repro steps ... I'd love to have them.

The fact that some of my data in managed (C#) land got corrupted gives me clues as to the parts of code that could have caused this. The reason is that verifiable managed code could not possibly do this. So it must either be native (C/C++ -- in other words Windows or other components that are loaded as a consequence) code, or some of the unsafe/unverifiable C# code (the code that uses pointers).

What were you doing before this crash? Effects? Tools?

Well, I opened Paint.NET, opened a file, started working on it and then I was going to open another file, messed with the view options and when I clicked open... *CRASH*
