I think SP1 should fix some of these errors. I mean all those error reports and the people sending them in had to generate quite a flurry at Redmond.
If Home is your forte, by all means run it like a mad demon LOL

I haven't had any issues on 3 PCs installed with XP pro. As I said before I had that IRQ crap on another laptop, and after doing the steps I stated above, it no longer does it. I actually think it was Norton antivirus or one of the system updates from MS, because when I did the restore I went all the way back, and now it works flawlessly.

I also think that XP will respond differently to different hardware setups and configurations. I am guessing that your Home version came with your PC right FG? It's probably configured to work best on your Hardware.
It is strange though that XP Home works great, but XP pro does not...
That is beyond me...
Just wait for the official SP1, update all your drivers, that is if you want to keep the Pro version.
