Hi all. I have been using Sketchup for several years, but never have I experienced this issue. I am building a model of my Uncle's house, which is currently at 3600.53KB. My Lenovo laptop exceeds all the Sketchup 8 system requirements and I have purged unused and fixed problems. Every time I open the model and start working for a few minutes, the cursor begins to leave a trail of points on all the edges it encounters, even recognizing midpoints, intersections, etc... I am still able to use the tools, but they all leave such trails as well and it fails to let me orbit or pan. Windows recognizes this as a program that is not responding and if I restart the program, all is well for a short period of time. In desperation to resolve the issue I even toggled the Intel processor 3D graphics all the way to performance, thus sacrificing quality. After that did not work, I reinstalled Sketchup completely. It seemed fine for a while but then gave me the BLUE SCREEN OF DEATH. After a reboot, the problem reoccurred. Can anyone please tell me how to fix this? I would really love to finish this model!

Thank You!
