My poor, poor Athlon... We (as in my domestic partner and me, LOL)finally decided it was time to upgrade, partially because the old 600 processor wasn't cutting it with newer games and most due to the fact that Poser has literally overtaken the old system. I have personal issues with the use of Windows XP but until I get some cash together to get Win 2K Professional for myself I'll put up with XP. So...as the post heading suggests...are there any odd issues or quirks between Poser 4.03 and related utilities (Tailor, etc)and Windows XP I should be aware of? Bleh...I hate change sometimes. :o)
