[Coco] NOS9 v3.30 Multivue not working correctly

[Robert Gault]

Would anyone check this on their systems?

The current nightly build of multivue_6309.dsk ( and presumably 6809 ) seems to 
be having problems with the NOS9 v3.3.0 OS, probably grfdrv.

With Multivue running, you should be able to change screen colors with Control 
from the menubar. This worked correctly with NOS9 v3.2.9 but now it seems 
impossible to set a white screen with black text and still be able to use 
Control. MVue starts with a white screen but immediately switches to a black screen.
