Never saw this before:Just switched to Win7 (64 bit), did a clean install of FSX (SP2), J41 and the new J41 SP1 recently released. When selecting the J41 in Select Aircraft in the Free Flight option, FSX crashes to desktop. I reinstalled the SP1 thinking that would do it but no dice. The update insisted on installng both the 64 and 32 bit C++ Redistributable if that has any impact. Anyone have any ideas?Shawn Cardwell
