X7 Technical Suite crash

X7 worked fine on Win7. After changing to a win 10 computer, all sorts of strange things happen:

After some minutes use: I can't alter dimensions of f.x. a rectangle, it sets itself to 0 or just a fraction of what I ask for. (I use dimensions in mm)

I can't choose Object Origin (the 9 squares button) more than once, it then freezes.

Sometimes the whole program freezes

X7 has to be restarted to resolve these problems

Anyone experienced something similar? And solved it?

Best regards & thx in advance
