With Windows 98, CodeWarrior R6 using OS 3.5 support, Emulator 3.0a3, with either
color debugRom or color nondebugRom I get an error
when running the sample program Test35 which is included in the 3.5 SDK. Stepping
through with the debugger indicates it occurs on
the FrmRemoveObject line in the InitAPicker function below. The error message is
"Test3.5" 1.0 has just read directly from memory manager data structures.
If I click "continue" it all seems to run fine.
Since it is getting to the FrmRemoveObject line, it would seem that CodeWarrior R6 is
using an old PalmRez?
Any ideas about what is going on here?
Thanks.
