Hi all, this problem has been discussed many times before, but as I was believing it was solved with the new tcas2v7.dll, last night it occurred once more (at least for me) :-( I was flying the 747 at FL360 online(IVAO) and an F16 was very close that gave me a tcas alert with a red icon on the ND. Then after 2 mins or so, FS9 hanged, displaying a message regarding the Visual C++..I looked for the TCAS2v7assert file in FS9 and I found this: (*i)->iptr != NULL: F:FS2004SDKTCAS2v7dllglobal.cpp:135What do you think?Thanks very much for any helpMatthew Abela

So any help from someone?Regards
