Hi Clutch, thanks for taking the time to answer. I hope my info helps. 1. just recently upgraded to Windows7?No, but I reinstalled FDSFX for the first time since installing W72. Issue always been there or just recently started happening.See above, so right from the start on W73. Happens with every aircraft or just one in particular? Only, maybe with a certain payware aircraft?All aircraft I've tried it on, all were default FSX (CRJ, B737, B 747)4. Happens with every Voice-set or just one in particularI only have the default voice set that came with the original download5. At what point does the crash happen?Right after either clicking the icon or selecting the panel from the Instrument View menu, I've tried both6. Is this constant and repeatable? 100% constant and repeatable, unfortunately. Hope we can figure this out, it's a gem of a little program that I'd hate to do without. Could it have anything to do with the panel bitmap? Thanks, Michael.
