This reminds me of something...
If it takes 12 seconds to start a SoftMaker Office app, there is something seriously wrong with your setup. If you care, start it with "textmaker -debug", and it will create a log file (tmlog.txt) that protocols the launch process. Might be interesting to figure where it's idling.
As for the test documents, is it possible to get them? We take pride in our DOCX and XLSX filters (and their quality has been confirmed by several reviews), so I'd like to check them out.
On 32 bit systems, SoftMaker Office inherits the colors and fonts from the system (if you are running KDE or Gnome). On 64 bit systems, this doesn't work yet.
And boy does it suck at that. We tried it out, and it is extremely unimpressive. Tracked changes are gone when you save to ODT, nested tables from ODT often lose their text, and object positioning is often wrong. Generally speaking, anything more than simple letters requires manual intervention.
Did they just repurpose the open source converter they commissioned? It certainly is the worst filter I've seen from Microsoft in a long time.
Research is to see what everybody else has seen, and think what nobody else has thought.
