Column problem resize with Firefox 0.9.2

Hello

It seems that there's a problem while resizing columns in Firefox 0.9.2 (may be other versions).
The problem is when I try to make the very LAST column wider it will not recognize button release event outside of grid/browser window and continue to resize column following the mouse motion while the button is depressed, thus grid (as well as whole page) becomes unusabe. Non of clicking somewhere over the grid, pressing ESC etc helps. The only way I've found is to reload the page.
However does it work with IE6

PS Sorry for my bad English, I'm not a native speaker :)

Sorry, I meant it does work with IE6.0 :)

Btw. there's another problem in firefox, this time with scrolling: when scrolling the grid with mouse wheel the scrollbar moves but the data doesn't.
IE6.0 is ok again
