I am using a MacBook to run SketchUp. The system I use is Mac OSX,
version 10.4.11. I have an Intel Core 2 Duo 1.83 GHz and have 512MB's
memory. I am experiencing a problem with tracking lines. When I make
a change to a drawing black lines appear to the area I make the
changes in. I also have had the program unexpectedly quit in the
middle of a drawing a few times. I have tried reinstalling the
program. It solves the problem for a day or two then the issues start
again. Does anyone here have the same issues and/or a solution?
