BIG Problem,.. box slow at following the cursor..?

BlitzMax Forums/BlitzMax Beginners Area/BIG Problem,.. box slow at following the cursor..?

I've got a big problem. I have a huge sheet of Types for Windows and Buttons which are Dragable by the cursor. My problem is when I drag the Window it's slow at following the cursor and the Buttons are even slower.. its not uber slow its just a few second delay.. it's smooth though.

(3GHZ, Windows Vista, 6600 GeForce 256MB, Using Flip 0/Flip 1.. tried with OpenGL and without.)

Anyone have ever experienced this? Is This bad coding or just BMax being slow? Cuz Basicly XPos=MouseX() which should be exactly on it at all time.

EDITED

I just tried Flip 0, it goes faster now but still not a 100%
because when I move it really fast my mouse overlaps abit on the buttons(which lights them up for a very short period of time) It shouldnt light up cuz i grabbed the window not on the button.. if you get what i mean

EDITED
How do I check for FPS(frame per second)?
