I've been using OpenOffice 2.2 in my GNU/Linux Ubuntu 7.04. My impression is that it is so buggy.
Importing Power Point documents takes forever (well, close to 5 minutes). I thought it was a specific Power Point file and specific to my notebook, but I saw it also happened to a friend of mine (on a different notebook and with a different file). So, it is not an isolated problem. When I tried to save the particular PPT file to OO format, OO 2.2 crashed. Of course, when I tried to recover the file ... it took forever.
There was also an occasion where my OO session crashed and it tried to open Writer.
This problem didn't happend when I was using OO 2.0. Should I revert to the older version? Or, is there a cure for this problem?
