I've been using Go-OO ever since 3.2 came out and I'm pretty pleased with it. It's much faster than OpenOffice which I now deem to be shit. The only bug I've noticed is that the windows sometimes refuse to close which can be a pain, I don't know whether this bug is common to the original OO.o but I'm now upgrading to 3.2.13 in the hope it's been fixed.
I don't see why people use the original version, not when there's a much better one available, probably because of lack of marketing.
EDIT:
It appears that I was currently using the most up to date version so I've needlessly uninstalled and reinstalled it.
Oh well, hopefully the bug will be fixed in the next version.
