launch error (newbie problem)

[daguk]

I would really appreciate some advice on getting passed this
problem.  When I install an application I wrote and attemp to run it, I
receive the following message in the form of a small dialog box.

Launch Error.
The application cannot be launched because of a system error.

This dialog box is within the PalmOS (not an emulator popup).  The only
option given me is to click OK, after which the system enters the Prefs
application.

I have searched through the knowledge base and the mailing list archives
without much luck.  I am convinced it is something I am doing
habitually, because (and get this) the problem occurs both in the source
I build with CodeWarrior in Windows AND using the prc-tools (ver. 2.8)
on Linux (Debian).

I have to believe this is a common error, because I know of at least one
other person that had the same problem (it just mysteriously disappeared
for him, though he may have accidentally fixed it) and just the fact
that I am getting the same error using two completely seperate
development tools (meaning, its not likely a corrupt resource or prc
file) seems to indicate this.

Anyway, I have included the complete set of files used for the project
below.  Please, if you can spare the time take a look and offer any
advice that you can.

-------------------------------------------------------

First I compile the source file below into sketch.o.  Then I use the
following command to write the prc file which I install and attempt to
run.

build-prc sketch.prc "Sketch" TRol sketch.o *.bin

---------- sketch.rcp:

FORM ID 1000 AT (0 0 160 160) NOSAVEBEHIND
BEGIN
  TITLE "Sketch"

  LABEL "Sketch" AUTOID AT (CENTER 148) FONT 1
END

---------- sketchRsc.h:

#define MainForm 1000

---------- sketch.c:

#include <PalmOS.h>
#include "sketchRsc.h"

static Err StartApplication (void)
{
 FrmGotoForm (MainForm);
 return 0;
}

static void StopApplication (void)
{
}

static Boolean MainFormHandleEvent (EventPtr event)
{
 Boolean handled = false;

 switch (event->eType) {
  case frmOpenEvent: {
   FormType *form = FrmGetActiveForm ();

   FrmDrawForm (form);
   handled = true;
  }
  break;

 }

 return handled;
}

static Boolean ApplicationHandleEvent (EventPtr event)
{
 FormType *form;
 UInt16 formID;
 Boolean handled = false;

 if (event->eType == frmLoadEvent) {
  formID = event->data.frmLoad.formID;
  form = FrmInitForm (formID);
  form = FrmInitForm (formID);
  FrmSetActiveForm (form);

  switch (formID) {
   case MainForm:
    FrmSetEventHandler (form, (FormEventHandlerPtr)MainFormHandleEvent);

    break;

   default:
    break;
  }
  handled = true;
 }

 return handled;
}

static void EventLoop (void)
{
 EventType event;
 UInt16 error;

 do {
  EvtGetEvent (&event, evtWaitForever);
  if (!SysHandleEvent (&event))
   if (!MenuHandleEvent (0, &event, &error))
    if (!ApplicationHandleEvent (&event))
     FrmDispatchEvent (&event);
 } while (event.eType != appStopEvent);
}

UInt32 PilotMain (UInt16 launchCode, MemPtr cmdPBP, UInt16 launchFlags)
{
 Err err;

 switch (launchCode) {
  case sysAppLaunchCmdNormalLaunch:
   if ((err = StartApplication ()) == 0) {
    EventLoop ();
    StopApplication ();
   }
   break;

  default:
   break;
 }

 return err;
}
