Can't use panel switchers on saved flights?

[strider 0]

More "strangeness" at my end. When I create a flight my panel switching buttons work fine. If I save that flight and come back to it later...pushing any of the panel switching buttons locks up FS9 until I get a shutdown (and the usual request to send info to MS...yeah...right! THAT'll fix it!! LOL). Anybody seen this one before? Between this and my non-working chrograph I'm thinking it might be time for a re-install of the entire 6,7,8 & 9 series. I'd rather avoid it, however, so I'll wait awhile for your responses and fly something else for now. Vic

A thought... Could installing the "PMDG_737_800_900_Model_Update" cause problems with a previously saved flight? Is the only purpose for this update to change the VC in the 6-700 or would it be needed by ANY user of the entire NG series? Vic
