Hello Yves,Any name brand plug-in card should do. It doesn't need to be an expensive one.I don't know how much memory you have, but buying more memory is another quick and cheap way to improve system performance.I can always take a look at the code, but as mentioned unless I can reproduce it (which I can't) I have no way fixing anything.Chrs,Bryan
