Blender has been crashing CONSTANTLY. I've been able to recover some of my work as I go, but it's gotten to the point that I have to span CTRL+S almost every minute.

[vxlcoder]

you're finding all the issues... sorry that it's giving you grief. taking a look now

[vxlcoder]

this appears to be the same issue as #1261.

could you try installing 3.4.2alpha using this temp link to see if you continue to get this issue?

will start investigating issue #1263 that you just reported.

also, are you working on a mesh that has hidden geometry? I'm trying to figure out how to replicate this problem and #1263, but I'm not sure how to trigger it. If possible, could you send your .blend file to retopoflow@cgcookie.com to help us debug, especially since you're saying it's crashing very frequently.

thanks!
