Blitzmax apps prevent screensaver running

BlitzMax Forums/BlitzMax Programming/Blitzmax apps prevent screensaver running

Windowed/Fullscreen makes no difference.

Been doing a bit of playing.

Ran this code:
Graphics 800,600
While Not KeyDown(key_escape)
	Delay 1
Wend
Screensaver works as expected.

I've been commenting out bit of my own code trying to locate the problem - there's something in the Blitzmax commandset thats causing this; I'm not doing anything fancy.

I've thus far ruled out AppTerminate(), DrawText, Cls, FlushMouse, Flip and the mouse lag fix.
