StretchBlt weirdness

Hi

I am copying an image to a window using the window sdk function StretchBlt. I am responding to WM_SIZE events so that when a user resizes the windows the image will size with the window. Running my app from labwindows everything is nice and fast most of the time.
However when I close the labwindows environment and run the app from it's exe file the resizing is *very* slow. I have traced this to the StretchBlt function. Can anyone think of any reason why StretchBlt would run faster with labwindows running ?

Thanks for any suggestions and help.

Glenn
