hi dave

thanks for your input, much appreciated

does the attached provide you with the information that you require? reading left to right; 1 + 2 are system info, 3 is SketchUp info - do I need to make changes to the latter?

have checked drivers + all up-to-date

I'm afraid I can't find anything about OpenGL support in Start > Settings > Display...

no graphics tablet no but thanks for the suggestion

hi guys

has anyone had this issue as per attachment? - as soon as any tool (line, tape measure, protractor etc.) cursor touches any part of the model it leaves behind a mark where and this then renders the programme unusable. to resolve this I have to close the programme and re-open

FYI, I'm using SketchUp Pro 7 but it also happens in SketchUp 8 which I downloaded to see if there was some issue with my version of Pro.

also this has only recently started happening, i've gone back and opened files I created before this started and some do not have this issue whereas others do

can anyone help, I'm completely befuddled

thanks

nidge
