Hi Jim, and thank you for you response. I tried in 32 bits first.. no input available in the ReadyPad, changed to 64.. it was a horrible mess in the screens of the G1000 so Im guessing no 64 bit version yet. (which doesn't matter since I barely use 64 due no xsquawkbox , no hurries there). I have also noticed that theTOPO screen in 3d view is way too bright; almost unusable. Is this a common issue? And last but not least, this my be to much, but I have noticed no animation on the stick, pedals and doors. not a biggie here, since what mater the most is the bird and how it behaves in the air. Just wanted to be sure this is not also an issue with my system which by the way is: a IMac 2.5 GHz Intel Core i5 4 GB 1333 MHz DDR3 OSX 10.7.5 hope this can be resolved soon.
