2.7 - Bevel, edge weight, bevel sets back when touching Factor

Not sure if it is a bug or if i do something wrong.

I add a bevel modifier
I set the limit method to weight
I enter edit mode
I adjust weight by moving the mouse

Then i want to adjust the weight a bit more by changing the factor. And bang, the bevel sets back, and cannot be tweaked anymore.

Is this a bug? Or where is my error?

Nobody an idea? I can reproduce this on two windows 7 64 bit pc’s with 2.70a. My main pc with a nvidia card and my laptop with a ati card. I have made a short movie that shows what i do. It is attached. 1.2 Mb

I think its a bug. If you change Mean Bevel Weight on N-panel, instead of Factor (T-panel), everything works well.

Thanks JuhaW. I have indeed made a bug report meanwhile. And it gots merged with an existing report then.
