I don't know what causes this, because it doesn't happen all the time, but I've been getting crashes when I'm selecting all of my uv shells in the uv editor window. This is the only time the program crashes for me, and like I said, it isn't all the time, so it makes it hard to figure out the exact cause, because I suspect there is something else going on.
Edit: It appears to be after I set the texel density, and I go to select the uv shells to do an align. I get a crash. This is actually pretty repeatable.
It looks like I am on an older version. I'll update and try it on the new one. How do I know when there is a new version, btw? I mean, is there an easier way than logging into my account every once in awhile?
