ussnorway: p.s, the flak Beamdog gets for making untested patches has been well deserved in the past but this time they did a very good job!... sorry if I wasn't clear about that
*nods* Beamdog really did get the 2.6.6 patch out VERY quickly. They actually had a beta version of the patch out within a week and held off on declaring it "official" until a certain number of independent users vetted and approved it on Windows, MacOS and Linux. It was available on Galaxy the same day it was released on Steam and the Beamdog client -- GOG just farted around for two weeks before finally updating the offline installers (and STILL haven't updated the patch notes since 2.5). I've given them plenty of flak in the past, but... giving credit where it's due: Beamdog did a solid job on 2.6.6.
I would highly recommend downloading the full offline installers for this version: it's a good baseline to fallback to in case things fly off the rails again in the future.
