BG Mobhack, I appreciate your comments on my Psychedelic problem. I worked on it for about two hours and found myself at "Driver Update." While there was no update for my video driver, it did kick me into a 'generic' driver status and it appears (so far) to have solved my problem (???). We'll see if it keeps on working. Thanx again.
OK, I think I found how to fix this problem in VISTA. Using VISTA "Display Setting," 'change the "Colors" drop down from "high (32 bit)" to "Medium (16 bit)." I have not had a problem since.
When completing the game and you really need the 'high,' go back and change, accordingly.
