Could anyone with a spare minute who is able please check this out, and confirm what the results on PC / IE 5.5 are? http://www.stowaway.net/dev/campbellrowley/site/Work It displays as expected in Firefox, Safari, IE 6, Opera 8, PC and Mac. On PC / IE 5.5 it should (in theory) look the same. On PC / IE 5.0 it should have flat colour instead of transparency. Mac / IE 5.0 and old Netscapes should (currently) die horribly. Again, TIA Joe
