WARN:Scrollbar:isc_HTMLPane_0_vscroll:ignoring bad or negative height

[tdk]

I keeping getting the following warning and stack trace, when I start my app:

00:00:00,001 [ERROR] 08:51:58.749:MOU6[E]:WARN:Scrollbar:isc_HTMLPane_0_vscroll:ignoring bad or negative height: -9 [enable 'sizing' log for stack trace]

I don't see any problems in my app but I'd rather have no warnings from my code.

I'm using GWT 2.0.4, SmartGWT 2.2, NetBeans 6.9.1, Firefox 3.6.8, Windows Vista Business x64
