That, mixed with internet, can lead to madness*. I have enough trouble getting the W3C defined elements to render logically cross-browser/cross-platform. * But yes, I have had to resort to such things on occasion. >Not if your browser is IE. :-( I get a kind of perverse pleasure in using PNGs on IE with a comment they will render properly once you switch browsers.

Yes. I'm tempted to do such things at times, but seems a very arrogant attitude to direct towards the visitor to the web site - "You have the wrong browser". My PhySci.codes site even (boldly) bears the 'Any Browser' logo.. There was this guy who was running IE 4 (I think mostly out of spite) who proudly mentioned that my pages always *crashed* his browser. I was glad he never got to *see* that logo. ;-) >Yes.

If Microsoft plays hardball, they should expect some resistance from those they screw. SignatureCanadian Mind Products, Roedy Green. http://mindprod.com Again taking new Java programming contracts. (Browser specific pages with message - 'upgrade to X browser') >>Yes.

You could equally argue that those 'screwed' people include the end-users, and telling them they are using the 'wrong browser' (which is something they may have no control over, think.. College, Library, Internet Cafe access) is just 'rubbing salt in the wound'. > You could equally argue that those 'screwed' people include the > end-users, and telling them they are using the 'wrong browser' > (which is something they may have no control over, think.. College, > Library, Internet Cafe access) is just 'rubbing salt in the wound'. 'encouraging them to fight for better browsers' If enough people complain that IE breaks the sites they are trying to use, maybe the college, library, cafe will address the issue. Certainly the cafe, which needs to please its customers.

Microsoft is screwing people. I am simply showing users a slightly degraded aesthetic experience if they use IE and putting the blame for it where it belongs -- on Microsoft for its buggy PNG support.
