CopyPaste 3.3.1a "solves" this problem by having this option turned off by default. "With this option off the CopyPaste Palette does not respond to all clicks in some programs. If you want the palette to be more responsive then you can try turning it on. If you have a freeze just turn this option back off for maximum compatibility."
CopyPaste 3.3.1a has been released. And just in time. Larry Katz reported a "bus error" system crash that he was getting when CopyPaste was installed. He found that he could cure it by turning of the "Get all clicks on Palette" option. (To access this, press the Command-C-P keys and then click on the icon to the left of the question mark in the resulting window.) Another reader traced a freeze on launch with Word 6 to CopyPaste; the origin of the freeze was likely the same option.
