Martin, Thanks for the response. Yes, there was something about SP2 which fixed the problem, and it seems to me that something I did last Friday seems to have undone the SP2 fix, and I can't restore whatever has been undone! I suspect that QuickTime is the culprit (with me accepting the updates which were available), but I have no hard evidence for that. I didn't think that changing version would help, but it seemed both polite to the people who suggested it, and a "good thing" to have the latest version in any case. I have just started the QuickTime player, and I'll see if that makes any difference. Do you know a way to check if the MM times is enabled? I could easily write a small piece of code do check this and enable them as an experiment. Could you perhaps send me a copy of the patch? Your help and suggestions are very much appreciated.
