Ditto on this end. I posted this issue regarding WB5 since I presumed it was the culprit. After a few more XP installs, I narrowed it down to IP Beta as well. It'd be ---REAL--- handy for Stardock to post a few hints regarding how to nuke a faulty installation or issue of this nature that results in a hang to the OS in such a fundamental way. Could never get past this without a wipe & re-install.
