Hmmm... about the two pages: maybe the skin engine has broken something there as well. It just can't handle dynamic content very well, so I've thrown it out again for now. The License should come from Help\English.license.txt (which should be installed by default!), the credits list built from an internal tool.
Regarding the history, that's spooky, since I haven't changed the IE code (except for multiple-startpage-support)!
I should have asked for "purge", not "clean", right, since you were speaking about usage tracks, where it should get completely purged.
I'm a bit surprised now though, since I've just seen that Usage Tracks Browser History is currently disabled and wouldn't even show. So I kind of wonder how you saw them at all
If I enable Usage Tracks Browser History again, cleaning works as intended.
Going to look up now why it was disabled in the first place.
