Thanks all for your insightful replies. Interesting case study.
@Rob:
Thanks for recommending Peter Nederlof's csshover.htc - my new year's
resolution was to write a site without crediting him, and while I still
have time, it won't happen this month! I'm going with this over
javascript because as it's MS proprietary code, it's almost certain to
be enabled for most users.
@Kay:
Some of my inputs were indeed submits, but type="button" doesn't help
for this particular problem.
@David:
IE7 does indeed support :hover on all sorts of elements. I have a vague
paranoid memory of certain circumstances breaking it, but that was back
in beta era.
The cursor:pointer is misleading in name - it generates a hand, not the
standard cursor - and in IE6 buttons give the standard cursor on hover.
Regards,
Barney
