#1 GfxLib refreshes incorrectly screen in W98

[antonigual]

The computer: P166 non-MMX, 80Mb Ram, S3Trio 4Mb PCI card.
Software: W98SE, DirectX8, FB 0.15 +0.16april
Windows resolution is set to 1024*768*32.

With the following program the screen refresh bands are
put rendomly in the window, and a correct image is
never created. The code uses only a PSET, no frills.
Using SET FBgfx=gdi does'nt solve the problem.

Sorry for the code, it was created for a short code contest
