Many thanks, I've got it working now.
Working in the Mambo theme, changing the default table width (2nd line of css) to 99% still looked horrible. This had me stumped until I tried 90% and it looks ok. I must have a particularly awful version of IE 5.
In the Karate Redux Blue theme I only had to change default table width down to 97% for it to look good...so I'll probably run with that.
One strange thing is that not all of the elements are resizing in equal proportions - the spotlight block and the notifications block shrank a bit more than everything else.
Another thing I noticed about the two themes that do seem to work directly vs the rest (imago 2&5) is that they have i) explicitly specified a width for the centre-centre block and ii) its set at <100%.
I assume that themes that don't explicitly do i) would probably assign the default table value (100%) to centre-centre blocks...I wonder if this is the main hotspot of IE 5 problems ?
