I'm using X2 on Windows XP and I've had my share of crashes and problems with it. I can never get X2 to open the first time I try and sometimes it takes three tries to get it to open. It doesn't matter if I use the Start Menu, my quick launch icon or the desktop icon. I get an hourglass when I click the icon but nothing happens until I do it a second or third time. X2 seems to be a very finicky program.
