Thanks Philip,
hText is a local variable. Local to the event handling function of the edit
form. The AddNoteDoneButton is the button indicating to save the data
(cancel works fine, it just exits the form) So I didn't think I would need
to free hText since it should go away once it is out of scope. I tried
MemHandleFreeText(hText) just for grins and that got me a memory chunk ptr
error. (which seems reasonable)
If I leave it as it is I keep getting an error writing directly to screen
memory. I don't know how one does that since I am only using the published
API's. So I suspect some sort of memory stomp perhaps?
Thanks,
Jim
