Remy, I'd love to say that that was the problem, but, alas no joy - still the screen saver kicks in. I've read and read and read the help file but I can't see whats going wrong here. I had a look at the article that you pointed out (i'd already read the one on closing NT screen savers) but I need to block the screen saver whilst my application is running. Just got a friend to test the TApplicationEvent VCL version, without the bitwise AND, running on an XP box and it stopped the screen saver - so who knows! Any more suggestions, Thanks anyways for your help Mike C "Remy Lebeau (TeamB)" <gambit47@yahoo.com> wrote in message news:3ede97d2$1@newsgroups.borland.com... > > "Mike Collins" <mikec@kr8.co.uk> wrote in message > news:3ede7c1b@newsgroups.borland.com... > > > if (msg.wParam == SC_SCREENSAVE) > > You should be masking off the wParam with 0xFFF0 before you compare the > value.
