------- Additional Comments From guowenzhong@yahoo.com 2006-23-10 12:41 ------- I noticed changes to toolbar.c in 0.9.23's changelog, so I upgraded to see if it would fix things. However, it made things even more bizarre.
With 0.9.23, the button will become "unhighlighted" about 0.5 seconds after the mouse lands on the button, even if the mouse is still on the button, *unless* the mouse has moved (still on the button though), in which case there is another 0.5 seconds of being "highlighted". This is the same in IE6. However, if the mouse leaves the button *and* toolbar during the 0.5 seconds, the button will stay "highlighted", as in 0.9.22.
I don't know which bug triggered this patch to toolbar.c, but it seems like the root of the problem is still not fixed.
