--- Comment #4 from Vincent Povirk madewokherd@gmail.com 2010-11-09 14:30:43 CST --- This sounds like a locking issue, as there's no GdipBitmapUnlockBits call following GdipBitmapLockBits. That would mean that the bitmap is already locked at that point and shouldn't be.
Normally I'd ask for the full +gdiplus log, but I have a change to send today that I'm hoping will fix most of these regressions.
