With FireFox 1.5.0.7 (win32) i have some javascript errors on Floating Windows with Tabs Widget at line 192 in floating_window_with_tabs.js => floatingWindowMoveCounter is not defined.
This error also happens on the demos page on the site ^^
The error doesn't always appears at the first time. If it doesn't, move some windows, reload your page and so on ...
Any idea
