The question is easy to answer I guess. (Tried to search here, didn't find an answer.) So.
The deal: There is a bug in OpenOffice (haha ..just one? :)), which prevents the spellcheck. You have to start it with right-click , run as administrator to make it work.
Tried also setting this at the 'properties', but it didn't work. But 'quickstart.exe' would be also enough to make this work. (OpenOffice's quickstarter). So I'd like to run it at boot, as an admin, like I'd do with right-click. How to do THAT?
(Actually there is a different bug for spellcheck on Win7. One have to run oowriter.exe as an admin, and then install the extension BY HAND from Program Files...\share...*.oxt. And THEN it'll work IF you run the app as an admin. (I'll buy SoftMaker's office as soon as the hu spellcheck arrives, but until then I have to make this work. Thanks for the answers in advance.))
