Issue with Hover in the showcase basics_interaction_hovers

Hi, I just tried the showcase basics_interaction_hovers with IE9 and with FF18 and the Hover text doesn't appear on the "Interesting Facts" field of the grid and also not on the "Severity" form label.

1. SmartClient Version: v9.0_2013-07-03/LGPL Development Only (built 2013-07-03)

2. IE9, FF18

Is it a known problem?

thanks
Marjorie
