Have Win XP Home SP3, Firefox 3.01. On rebooting I get a warning message just before the sign in pane opens which advises " 1st Delete program not found--skipping auto check" Apparently this lack causes me-at times- to have to click on the "X" twice to close a program. Quite annoying. I have run sfc /scannow twice with no apparent effect on fixing. Appreciate any other possible solutions.
