My collegue has something very strange happening. Ever so often Open GL gets activated by itself for no apparent reason. The last time around he had switched it off only to come to the realisation that the "dynamic highlight" option wasn't turned on any longer. When he then switched that on the next drawing he opened was slow in responds again and so he checked and lo' and behold Open GL was turned on again.

Opening a file to come to the conclusion some setting is wrong, closing it down, changing setting, open drawing ... rinse and repeat..... it quickly becomes a drag.

He's using a SW approved system (workstation HP) with a GX 1700 Graphics card with the SW approved driver for it so there's no reason why the system should think that Open GL is needed.

Any suggestions are welcome.
