[Jmol-users] Mac mouse button bug

[Miguel]

Frieda & others on Macs:

Here is some source code and object code to test mouse events.

Runs on any system with java 1.4 or greater

You can run it by saying.

Download it to some directory
bring up a terminal
go to that directory and type the command:
 java ShiftButtonBug


Source code is provided in case you are interested.

I cannot file the bug unless/until someone tells me which sequence of
events is not being properly reported.
