I have two global variables:

In StartApplication() I do:
downloadX = (Char*)MemPtrNew(1024);
downloadY = (Char*)MemPtrNew(1024);

I stand corrected. The warning/error message that I was thinking about was
freeing a freed handle (i.e. the error message is Free handle).
I apologize about that. I should make sure I don't have my wires crossed

The simulator will, however, tell you that you are freeing a locked chunk.
Are you sure about that? I can't find anything in the sources that
checks for that when freeing a handle. What message does it give
you? Perhaps I could search on that.
Freeing unlocked memory is OK. There is no need to unlock a locked block
first. It should not cause the crash Chris Massey is reporting.

Looks to me like you're trying to free memory that you didn't allocate. Probably the
memory manager is complaining because it can't find the chunk header, which would
happen if the memory in question is just part of a larger chunk, such as the chunk
allocated by Palm OS for the form.
