Thanks Christopher. I had already done your tests and others. One 
interesting test, which eliminates T3 as the source of the problem, is 
that when I arrange for a horizontal menu to have two-levels, it renders 
the hover properly. Therefore, the .htc file is found and the version of 
T3 does not matter. Both CSS and HTML are valid except for extensions. 
However, I shouldn't think the CSS for extension would matter if I have 
already proved that the hover works. I guess I'll trim the menu CSS down 
to the barest of code to see what I can find. Thanks for thinking . . .
