Hey I have another feature difference between IE8/Win7 and FF3/Vista
In this thread:
The code pasted turns itself into a three line output and wraps itself around on IE8 (ie - it has lines 1, 2, 3 in the gutter and line 3 is very long and wraps round to form another 40 or so lines)
On FF3 this morning I come back and its a two line output with no wrapping on FF3 (ie - it has line 1 in the gutter, splits on the two <br> tags and then travels off right into infinity with a very long horizontal scroll bar).
Means that the message is basically unreadable for FF3 readers (however View Plain is a usable workaround - just not colour highlighting)
I guess its just something to watch out for after the 2.0 upgrade.
