I have been reviewing event logs in order to debug a problem. I do not
understand the sequence of events when you exit one form (a dialog box with
an ok button) and return to a base form.
62048.591 (63236): <- EvtGetSysEvent: penDownEvent X:9 Y:142
62048.601 (63236): <- EvtGetEvent: penDownEvent X:7 Y:62
makes sense, pen down in the ok button
62048.601 (63236): -> EvtAddEventToQueue: ctlEnterEvent ID: 12004
62048.601 (63236): <- EvtGetEvent: ctlEnterEvent ID: 12004
makes sense, entering the ok button
62048.601 (63237): -> EvtEnqueuePenPoint: pen->x=-1, pen->y=-1.
62048.601 (63237): <- EvtGetPen: screenX=7, screenY=62, penDown=0.
I don't understand what these are for
62048.611 (63237): -> EvtAddEventToQueue: ctlSelectEvent ID: 12004 On: 0
62048.611 (63237): <- EvtGetEvent: ctlSelectEvent ID: 12004 On: 0
makes sense, pen must have been lifted, and the ok button was selected
62048.722 (63237): -> EvtAddEventToQueue: frmUpdateEvent ID: 1500
makes sense, this is a call to FrmUpdateForm
62048.842 (63237): <- EvtGetEvent: winExitEvent Enter: 00004AB4 Exit:
00005AA6 Enter Form: "Flight Plan"
62048.842 (63237): <- EvtGetEvent: winEnterEvent Enter: 00004AB4 Exit:
00005AA6 Enter Form: "Flight Plan"
makes sense, the old form is gone, and the new form is in place
62048.852 (63237): <- EvtGetEvent: frmUpdateEvent ID: 1500
makes sense, the update event generated by my call to FrmUpdateFrom
62049.042 (63237): <- EvtGetSysEvent: penUpEvent X:9 Y:142
62049.042 (63237): <- EvtGetEvent: penUpEvent X:9 Y:142
this is where I get really confused. It appears that this is the pen up
that resulted in the ctlSelectEvent
(the ok button on the previous form).
I am surprised that this event is generated since I would have assumed
that the pen up would have been
handled by the system when it was tracking the pen before it generated
the ctlSelectEvent.
62049.052 (63238): -> EvtEnqueueKey: ascii = 0x00F9, keycode = 0x0000,
modifiers = 0x0000.
62049.052 (63239): <- EvtGetSysEvent: keyDownEvent Key:0xF9, Modifiers:
0x0000
62049.052 (63239): <- EvtGetEvent: keyDownEvent Key:0xF9, Modifiers:
0x0000
the penUpEvent results in a keyDownEvent being generated on the new form
62049.132 (63239): === ERROR:
*****************************************************
62049.132 (63239): === ERROR: ... SysFatalAlert with the message: "Table.c,
Line:94, Text not usable".
62049.132 (63239): === ERROR:

This does not normally cause a problem, but after 2.7 million gremlins, this
problem occurred.
Any help would be appreciated,
Laurie
