Ah, it turns out NetrekXP does not use SDL, guess it branched off before that was added. Since sound mixing would be a really good thing, I'm going to look into putting it into NetrekXP following what was done to the COW client. I looked over the Changelog for COW, it seemed SDL was one of the larger changes. Any other things that were added within the last 6 years that might be worth porting over to XP? Bill
