MultiMaster 2.0x is partially incompatible with MacDraw Pro 1.0v1. If you use the Hide windows feature in MultiMaster while having a large clipboard in MacDraw Pro, MacDraw Pro will crash.
MultiMaster is a program launcher very similar to On Cue. It is included with Now Utilities 2.03. This problem has been reported to Now Software Inc.
Note: MultiMaster 3.0 has not been tested for compatibility with MacDraw Pro.
