Win9x has unlike WinNT/2k - at least this is my experience - a limited number of window-handles.

After starting the application Tutorial5 (with some other apps already open) I have
53% System ressources
58% User Ressources
53% GDI Ressources

After scrolling down and up 7 lines (nothing new is displayed) this decreases to 47-58-47,
srolling down/up again -> 40-58-40
---"--- -> 34-58-34 ...

and so on.
Note : Nothing new is displayed ever in the grid, only the font of the selected line is changed. Even closing the connection to the DB and re-connecting does not free these ressources.

I hope this helps to resolve this problem...
