Welcome to SolidWorks forums David.
No offence but first of all move your discussion to install to general tab as this doesn't belong to toolbox category. Use move discussion option under Actions on the right side of the post.
Secondly, do you've antivirus installed on the machine. If yes then disable it and reinstall SolidWorks.
If possible install SW2011 SP 5.
Next question: Why can't you use Win 7 with 64 bit version of SW.

Thank You Mr.Gupta , i've changed the category and i'll try re installing SW w/out the anti-virus , maybe it's that. If not i'll go with SW-sp5
perhaps I didn't explain to well , but I can use the program perfectly and all functions seem to works except Sketch picture. Like I said the funtion loads but it freezes when loading the new box to choose any option and finally crashes.
