The chances of this problem being Palm OS Emulator specific are
pretty low. There are no known differences between launching on the
two environments.
There are a few reasons for the application not being launchable.
For instance:
* There could be insufficient dynamic heap space to allocate the
application info block.
* There could be insufficient dynamic heap space to allocate the
application stack.
* Some previous operations could have somehow used up all available task IDs.
* The .prc file could be malformed (for instance, 'code'(0) or
'code'(1) could be missing).
I'm not sure which of these is most likely, but that's where I'd
look. (Actually, what I would do is modify Poser to tailpatch
SysAppLaunch so that I could examine the result code it returned.
But that's just me. Perhaps Blake could use PalmDebugger to break on
SysAppLaunch, step over it, and look at the result code in register
D0.)
