I have an installation of Word 2007 with the Quark XML Author plug-in recently added. When I try to access Word Help by clicking the tiny ? in a circle at the right hand end of the menu bar, the Word Help pane opens, but it is blank. Normally it opens populated with help topics. Also, my cursor changes to an hourglass, and it remains that way until I exit Word. If I type anything in the Word Help pane, I get the same result. At another machine with Word 2007 + Quark XML Author, the Word Help pane performs normally.

F1 gives the same unsatisfactory result.

My tech tried uninstalling and reinstalling the Quark XML Author plug-in, to see if that fixes the problem. It did not. All suggestions welcome.
