Ok, here are the screenshots from my recent windows build of koffice (kdepim might follow).
kspread died when I entered '!' instead of '1'
kivio cannot delete objects - this probably doesn't work in other koffice apps too.
kexi looks wonderful, but is the only app from the kde project that does not detach from the cmd.exe window - why I don't know.
and last: kword does not like @ signs - this was fixed in kate already by chehrlic (function keyPressEvent) but I couldn't find it in koffice (I haven't looked a lot).
I will post the kdepim screenshots later - kmail isn't working anyway, kaddressbook has severe problems and kontact doesn't like me.
