That's great, thanks - much appreciated!
So 1.6.6. was built using a different framework than the previous versions and 1.6.6 is considerably more buggy than the previous versions... most likely not a coincidence I would think.
Please note that there may well be inherant issues with older versions too (as they were built on older framework, not that used for 1.6.6).
Thanks a lot to audiosabre and especially Compyfox too, for offering previous versions...
