Hi - that really surprises me that you didn't hear back from e-on about the tooltip problem.  I had an answer within an hour of filing the Object Size bug report - albeit only "Thanks for the report - I'll forward to our development group." from Lee.

If I were you,  I would post a question on the e-on user forum too, and maybe on the Cornucopia forum.  Granted, pretty much the same people frequent those forums as are here on Renderosity, but it's annoying enough to be worth the extra effort.
