Windows can t find ...............

A week ago, I think it was after opdating FF to ver. 7, I get this error when I try to open a webpage from a bookmark - shortcut file:
windows can t find [the page] Be shure that you have typed the right address ...............

BUT the right page opens below the error message, and it is only if FF is closed the error appears.

I have made a system restore to two weeks back, the error is still there,
I have uninstalled FF and reinstalled ver 6, the error is still there,
what can be wrong here ??????

After uninstalling FF the shortcuts did work perfectly with IE8

winxp3

TIA
