MacVision Problem

[rmusick]

Can someone help me with a problem here.  I have a HP DC7700 Small profile with the native Video Running Xp.  I used quick res to drop the resolution to 640x480x32 and 640x480x16.  I attach the Monitor and boot up looks great MAME/MALA loaded on it great..
Here is the problem.
Yesterday my nephews were playing the game and intermittently the orientation would switch to vertical then back to horizontal,  this went on for several times.  I Dropped out of mame and when I went back the screen blacked and I heard this rapid click/ like it didn't now what mode to be in.  Thoughts?

Ctrl-Alt-Up Arrow

Always fun to nag no-no's with it

Ctrl-Alt-Down Arrow will turn everything upside down etc. It's best to turn it off for Mame machines. Yeaahhhh, another excellent Windows "feature"

Thanks I will Definitely disable this "feature"  Any Ideas on the Black screen?  and the rapid flickering.  I tested it again yesterday and sure enough,  You can boot the computer up, go into windows and load MALA up fine, when you start a game it goes haywire.
