Have installed NT 4.0 release and Delphi 2.0.. got the following problems
 wich I didn't have in Win95:

 * Hard to install components
 * I a image is on a beavel then it dont shows until I move the form
   most object on a beavel or ?anel dont work properly.
 * Speedbuttons with the same groupindex remain dowm when pressed on
 * When I draw on a bitmap it dont shows...

  Running on the S3 videodriver deliverd with NT4
  Thats all for now... I'm back on Win95..
