Management Central is running but when I try to open it I get "An unhandled win32 exception occurred in cwbunnav.exe" It opens a Visual Studio Just-In-Time debugger. Selecting Yes to debug doesn't work because the source is unavailable. Selecting No (and when exiting the debugger), the iNavigator terminates. So far every thing I've read leads me to believe I should be able to open it. We're on v5r3, my iSeries Access is v6r1. We tried this on 4 PC's (one at Access v5r3) with the same results.
