Hi Micah,
Since the last changes of the server, I note a problem that seems to be due to
resizing of widgets.
The following code highlight the problem.
The 'toggle' button juste toggle the size of the ~laucher~ between 0 and PG_S_ALL.
And when the ~laucher~ is graphically corrupted, you can retrieve it as good by
changing the size of the window.
I hope this is of some help for you,
-philippe
