>For those of us in SP3 or earlier land, what' different?
Nothing to do with Queryunload or NoDefault, AFAIK :)
Seriously, though, I only have SP4 on a test machine, but I notice absolutely no difference from SP3 for the apps compiled & run under SP4. I'm sure you know about the list of bug fixes and additions at the MS site, but I haven't found anything worth the trouble of upgrading hundreds of runtimes. All my apps will stay SP3 for now except for the test machine. OTOH, I haven't found any problems with SP4, either.
