Hello all,

thanks in advance for any suggest and opinion.
What I want to talk of is the behaviour of Sketchup after a not foreseeble time of work.
I find the program quite simple to use and user-friendly. After having made some model, not so complicated also, the program starts to be bizarre and actually not user-friendly and usable anymore. For example, imagine we have just a cube. i find hard also to pull and extend a face of the cube at all. It's like if some good skill of the program becames deaf on the command. Another example is the positioning of another figure in the generic face. Something of impossible to handle. Now, I cannot understand this behaviour because actually at the beginning of the use it works perfecly. Unfortunately also if i quit it and reload sketchup it's already compromise. So I cannot find any clue and answer to this tricky problem. The only thing that I can imagine is that, growing a model I touch (and do it several times) some environmental option which change the friendly management of sketchup.
Now, I solved the problem a couple of times de-installing and installing the tool again, but I can't stand this behaviour anymore.
I hope some of you can tell me something about that. Can it be due on my laptop and my graphic board?

Thanks a lot
