Problem: COLTS II version 2.02 is behaving sluggishly in Windows. When trying to switch between different panels COLTS takes a long time, the panels become blank, or COLTS locks up (stops responding to input). Note: This only applies to COLTS II version 2.02. You can check which version of COLTS II you have by clicking on Help | About Colts II and looking for Version.

Solution: Reboot your machine. Don't run any other programs except Runway when you open COLTS II, and once COLTS II is open you can close Runway. This is a known bug with COLTS II version 2.02 and it should be fixed by the campus wide release of the updated version of COLTS II.
