SOLVED! The old battle between QuickBASIC 4.5 and XP.

[Ralph]

I think that it was about a year ago that, heeding the consul of Na_th_an from Spain, I started to look for what programs were running in the background, as one of them was strongly suggested was the culprit of my problem in running QuickBASIC programs with graphics (using any SCREEN other than SCREEN 0, the default). I was able to see which programs, out of a total of 27 that were shown in a window, had their checkbox checked or not checked, and, by a process of elimination, found that flatbed.exe was the culprit!

Now, I don't remember how I was able to bring that window up! :???: Can anybody help me regain that knowledge?

EDITED at 10:15 am.
SOLVED: Hit Start, Run, enter msconfig, click on the rightmost tab, Startup. There are the programs that start running at startup!

I had been searching for the answer since last night, and, finally, I found it on the Internet just a short while ago.
