Very interesting. I see you're using the 8.1 update -- good. I'm not sure what is causing the crash; it is a NULL pointer reference, but without a test case here, I can't tell what is causing it. If you contact Metrowerks technical support, we can try a few different things to try to find out what is happening. You did the right thing by replacing the library. You might want to try rebuilding the libraries using the "Palm OS Runtime.mcp" project in the CW for Palm OS Support folder. If the library was bad, this should fix it. Also, if you use the A4/A5 runtime and your project isn't set to expanded mode (see the 68K Project panel), this could cause an error -- I'll have to check to see how the linker handles that. Thunks shouldn't affect anything at the link phase, only at runtime. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
