Hallo Fabian,
hilft Dir die folgende Beschreibung weiter?
-------------------------------------
More specifically, hardware accelerated OpenGL... Try this..
1) Start Rhino
2) Go into the OpenGL Settings page and select a Software Emulation mode.
3) Close Rhino.
4) Reboot your machine
5) Verify that tooltips are working
6) Start Rhino, load some models, shade them, render preview them, etc,
etc...
7) See if tooltips continue to work or if they're broken again.
Note: Don't forget to change back to your accelerated mode once you're done
with this experiment.
