Does anybody else have trouble with SolidWorks lagging between commands (switching sheets, windows, or adding new views)? Seems like it takes a good 30 seconds to a minute once I do one of those things before I can do anything else. My rebuild and save times are both consistantly over 1-2 minutes. Has anybody else ran into the problem. I've got 4GB of memory on my computer so I'm sure that's enough.
