QB1.1, problems with using PAINT to erase graphics.

[Guest_imported]

I am trying to use a paint statement to clear graphics on the screen. I have noticed several strange things that occur when I try this:

After a certain number of sweeps, the paint statement stops doing anything.

The paint proceedure seems to only cover certain parts of the screen, (say when I have a circle flying around the screen, when it reaches the edges of the screen it doesn't get erased by the paint.


Here is a paint tester I made:

SCREEN 13: CLS
COLOR 7
FOR x = 1 TO 20
CIRCLE (92, x * 4), 10, 30
a$ = INPUT$(1)
PAINT (92, x * 4), 4, 7
PRINT x
NEXT x

The numbers should each be surrounded by color as the program loops, but they are not.

I looked in Qbasic help, and it has some other arguments that seemed to suggest a way to paint repeatedly, but it is too brief for me to understand.
I wonder if the problem could be related to the type of computer I have: 700mhz, 30gig, Windows ME. I have noticed that bload and bsave do not work properly on some computers ,and I wonder if such errors apply, somehow, in this situation.

ANTI-STUPID NOTE:
Thank you, but I do not require other suggestions for erasing graphics. What I'm doing seems to work best with the paint statement.
I fully understand that paint will not erase colors which are defined as the border colors.

if you do not want other suggestion you will not be able to do what you want to. try using line(upleft)-(downright), color, bf to draw a rectangle the same color as your background.

Do you know why the paint statement doesn't paint after a certain number of sweeps
