I think you want to set the fields text handle to null while you're mucking
with it...
MemHandle theHandle = FldGetTextHandle(pField);
if(theHandle)
{
Boolean fDirty = FldDirty(pField);
FldSetTextHandle(pField, NULL);
Char *pszText = (Char *) MemHandleLock(theHandle);
TxtGlueStripSpaces(pszText, true, true);
MemPtrUnlock(pszText);
FldSetTextHandle(pField, theHandle);
FldSetDirty(pField, fDirty);
FldDrawField(pField);
}
