Thanks lhclin and taodr and everyone for the heads up on SP1. Just called eSignal and they said that someone at Tickquest had been in touch with them about this but the guy I talked to said from reading the interoffice email that they didn't realize you were talking about SP1 but thought you were just talking about Win XP in general which works fine with eSignal they said. Anyway, they're going to install SP1 now and test it next week and get back to me so I'll let you know what they say when they do. Also I use CyberTrader Pro and I'm going to contact them to see if there are any issues. I'll let you know.
Finally got around to installing XP Pro on my new hard drive. So far so good. Not as many hassles as I had imagined. I'm working at maximizing my system resources by eliminating a lot of the unnecessary background eye candy features. I'll let you know how it goes.
If anyone is interested in a Full and Sealed version of Microsoft XP Professional Let me know. I can let you have a good deal on mine. I won it in a promotion. I ordered it directly from microsoft.
Assuming new hardware and supported equipment, I would opt for XP pro (I have twenty computers, runnig Solaris, FreeBSD, Win2K, XP, Linux, etc, so I am not really biased.)
Here is a sight that may make XP a little more friendly...
