Well, I had a couple of problems (seem like bugs) and started back with Word again, but then Word totally crashed a lost a lot of edits so I figured "Can't be any worse than this crap" so I'm back with OO.
Loads slow on startup, and takes a while to load files. But: This seems to be due to it actually loading the entire file before displaying anything. Word would "load" a large file quickly, but then to flip to any particular page I'd have to go into Print Preview or something so it could paginate everything properly.
I tried plopping a spreadsheet into an OO Writer doc this morning and it seemed to go off without a hitch. A JPG graphic also seemed to work as advertised, too.
There is one thing that has defied explanation so far: setting the default font size. I can get the info for the actual font but the font size doesn't show up in that window. Changing the toolbar icons is also eluding me at the moment.
Still, bloody good job. I could see places replacing Word with this easily.
