If you click on a link in an item description, and then
close it with Ctrl-F4, the space bar is dead.
This is because of WinGUIMain.cs line 8095:
IHTMLDocument2 htdoc = htmlDetail.Document2;
In this case, Document2 is null. htmlDetail.Document is
valid, however, and casting it to IHTMLDocument2 fixes
ie, replace that line with:
IHTMLDocument2 htdoc = (IHTMLDocument2)
