I would want to rule out whether this might be a video driver issue. To do this, launch SolidWorks but don't open any files. Go to Tools, Options, System Options, Performance. Near the bottom of the screen, find the "Use Software OpenGL" setting. It's probably unchecked--CHECK it. Now open the part or assembly you were working on and see if you can use the appearance callout functions without crashing. If so, then the problem is likely your video driver or with your card-specific video settings.
Of course if this doesn't correct the problem, repeat the above steps and UNCHECK the Software OpenGL setting, then give your reseller a call and they can help you troubleshoot further.
