Hi

I have a program that seems to run fine in the emulator except that
whenever I try to close the program I'm told that I have a memory
leak. I've figured out what statement is causing the leak but I can't
figure out how to fix it. This code is called when a certain form is 
being initialized:

double psaVal = pronData->pretx_psa;
char* psaStr = new char[6];
	
if(psaVal != NO_VALUE) {
	doubleToStr(psaStr, psaVal, 1);
}
else
	psaStr = "";
	
SetFieldHandle(GetObjectPtr<FieldType>( PreTxPSAField), psaStr);

This code simply creates a string from a double and sets a field to
that string. The memory leak was caused by the "new char[6]" line so I
put in a deallocation function that would be called when the form
receives a frmCloseEvent (I made sure to set handled=false):

void PreTxCleanUp() {

        FormType* frmP = FrmGetActiveForm();
	FieldType* field = (FieldType*)
FrmGetObjectPtr(frmP,FrmGetObjectIndex (frmP, PreTxPSAField));
	
	MemHandle refs = FldGetTextHandle(field);
	
	if(refs != NULL) {//  && MemHandleUnlock(refs) != memErrInvalidParam)
{
		FldSetTextHandle (field, NULL);
		MemHandleFree(refs);
	}
	
}

This function doesnt give any errors buy it also doesn't fix the
problem. Every time I open and close the form in question it creates a
leaked memory chunk. Am I not de-allocating the memory properly or is
there a problem with the emulator? Also, if the memory leak is caused
by a variable local to a certain form why isn't the emulator telling
me about the leak as soon as I close the form as opposed to waiting
until I close the whole program? Thanks in advance for any advice.
