Hendrik,

We have encountered the exact same problem as this on our two headed
workstations. The problem is due to a rather strange bug in IDL.

Apparently, any IDL application with bitmap buttons will run perfectly
well on screen 0, but it locks up on screen 1.

The solution:
1) Don't run your application on screen 0 !

2) Change your application so that the buttons have text labels instead
of bitmaps. This could even be done automatically inside your program by
looking at $DISPLAY and deciding when to use bitmaps and when to use
labels

3) Create your own "buttons" based on draw widgets. I think David
Fanning has some code to do this.

The other problem we've noticed is that running IDL on a dual screen
workstation ties up two IDL licenses. One for screen 0 and one for
screen 1 - even for the same user.
What happens when we move to workstations with 3 screens ?

Regards,
Justin.
