Thanks for the details! I was searching under FoxPro on Microsoft's site and not getting very far.
Now, is there a utility to run that would fix my source links? The X is back, but when I click on it, it brings up a window that shows unknown source. Specifically, in the Proof window under the box where it says CDO Evidence, it says 0! Unknown Source ### (where ### represents a source number). When I click to add an existing source, a window comes up showing a list that basically says Unknown Source repeatedly. It looks like all my sources are trashed (or a pointer may simply be pointing in the wrong location).
One of my toolbars is missing as well - the one with the icons on it.
