Wow, this makes me glad I have not updated TSX in over a year and may never do so again. They just lost my annual subscription and may lose me as a mount customer altogether if this is true. Who do they think they are, Apple?! Have not posted here in a long time but I am glad I read this thread and will avoid updating TSX. In fact, I am still running 2.4.X SGP and an older PhD. Nothing I can see has been added to either that would make my imaging easier so it it is not broke (and so far it is not), I will not fix it!
I may try newer versions of SGP and Phd on a test PC but TSX is gonna stay as is until I am sure SB did not F this up for SGP users!
