The PC was purchased from Dell with XP Home installed. I've used the tabs many times before, but not for a while. Tried setting up a new user account, same problem. I do have access to the tabs in safe mode, but can't make changes.
Tried kellys-korner-xp.com/xp_tweaks.htm, Line 285, right side, Restore All Display Tabs. The only thing that accomplished was to bounce me into WinXP's standard theme and screen saver, which I don't want (and now can't get rid of). Still no tabs. Tried a few other tweaks from that site, no luck.
Also tried deleting everything at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System - no change.
Any ideas? Thanks!
