try putting the command View.Update

that should get rid of the flickering.

It goes at the bottom, before the end if.

You can add to your setscreen with an offscreenonly then put in a View.Update or change your setscreen to a View.Set ("graphics, offscreenonly") and still add in the View.Update to the program near the end.

in addition to that, instead of setscreen("graphics")

put setscreen("offscreenonly")

it will stop the flickering. =)

Set your screen to offscreenonly.
View.Set ("offscreenonly")

This implements what is called a backbuffer. It makes your program draw everything to the memory instead of the screen. When you want to take what was drawn in the memory and put it on the screen, you flip the backbuffer with this command:
View.Update

Call this as soon as you are done drawing a frame.

So if you put both in, they cancel each other out and makes the computer do useless calculations?

I'm not sure what you are asking, so I'm just going  to say no (a very confident no).

By default the window will refresh every chance it can get, up to once a millisecond (never happens).

View.Set ("offscreenonly") makes it so that the window will only refresh when you deselect the window then reselect it. Alternatively it will refresh when the function View.Update is called.
