My XP install seems to be a little buggy...

-"I've installed XP loads of times elsewhere and not had probs."-
On other Boot Camp partitions?

-"Is this common?"-
I think you answered your own question on that one if the question above is yes.:)

Well, Boot Camp isn't perfect but neither is the Windows installer sometimes. Between the two, "issue's" can occur.

You might un-install then re-install FFox just to double check it. From what I've come across "short cut's" have their own issues on a normal PC install.

You could reinstall Windows again to be able to start fresh as it were but I would try Norton first.
I don't think there would be any reason NOT to use Norton's as Windows is pretty much 99 percent native. Worst case scenario you could re-install Windows if it messed it up more. I haven't really heard of any of the disk utility's like Norton's, etc, messing up Via Boot Camp.

From what I understand Boot Camp only transfers the basic Windows version of the Mac drivers for continuity, like the Video card, keyboards, ethernet, etc, to be able to translate between the two.

Every thing else is Windows problems and Windows alone. If Internet Explorer works then it's a problem with FFox not the install.

Hope that helps.......

Well, not picking on FFox but, good as example as any, it's not so much buggy in it's self as when it installs it becomes buggy. Doesn't matter if PC or Mac programs. I rarely have problems but after reading about other people's problems it happens more often then people think.

You have to figure that after how many thousand's of disks that are burned how many didn't quite make the grade. And then a speck of dust on the CD/DVD and you have a 50 50 chance it will work. Same with downloads, how many millions of miles of wires, routers and switch's and airwaves etc, it has to go through and it really amazes me how many problems we DON'T have.

Have fun....
