Qavimator issues

I've been using qavimator for a little while now. However I've run into one exceedingly frustrating bug I can't seem to get rid of. Of course it's intermittent. Once in a while, I am working in Qavimator, and running second life. I'll go between the two to adjust an animation so it looks the way I want it to in SL. The problem is somewhere along the way, the animation either stops working (as if it was looping the first frame). Or it will corrupt the file and I can no longer open it in Qavimator without it crashing. Anyone have a remedy for this?

On another subject. I hear IK doesn't work in Qavimator. I didn't even realise it had IK. How come it doesn't work? What happens exactly?

Are you saving your QAvi anims as .avm? (Only exporting .bvh for import to SL?)

Maybe change revision numbers as you save so if one gets corrupted you can at least go to the previous one? I'm afraid (fortunately) I haven't had your problem.

I see a new version was released last week, maybe try that? You never know, maybe something has changed so it won't conflict on your system?

How come IK doesn't work? I'm sure they would love someone to contribute to making it work! (What happens? Things go haywire instead of where you'd want, like knees bending sideways in toward each other rather than forward if you lower the hips...)
