>At this same page there is a UT Login link; once this one has been used, then it works fine. This keeps on working until the browser instance directing to this Login link is closed, and started again. So somehow the page where UT originates from is related to the problem (avoiding it). Hence, starting UT directly from a new browser instance (and logging in) won't allow the FRAMERMENU to be found as an object.

Note also that you can have unexpected behaviors if you load multiple instances of the messages area. This is built to only support one messages interface.
