Drawing is blinking, when working on it.

Hi.

On my colleagues new computer in Lithuania, the drawings in plancad is blinking, when she is working on it. It doesn't matter it seems, if the drawing is simple or have hatches or if I am "on" her computer (remote control) or not.

What can cause it?

They said it stopped now - but if they get it again, that could be something to check...

Hi. Just got a message from Nvidia, that there was new driver for my graphic card. Installed it - and now my drawings are blinking 3 times, when I change text and 1 time if I press "save"... I am of course not sure if that was the case also before I updated the Nvidia driver, but...

Graphic card is Geforce GTX460M and I am by the way using an external monitor Asus VK278Q, but I don't think that should mean anything.

Can be. How would I do that. Reset Windows to before I installed the driver?

Ok - but now I just started to work in Dietrichs - and now the drawings are not blinking - at all. But listen here: When I was finished to install this driver, my short cut icons on my desktop was completely messed up. So I cleaned it up and deleted also a few of them. Later I was out and I think I just turned off the external monitor - or maybe I was just eating dinner. But anyway, when I came back the desktop was back to what it was before. I have no idea what have happened. Maybe the driver rolled back itself, because there was something it was not compatible with in my setup... (?). I probably could check, by checking version number of driver. Perhaps I will do that later.

Ok, I have checked the driver version - and the installed driver version actually match the new driver version. So maybe it just needed a shut down of the computer and turn on next day, in order to take effect.
