Maybe your problem is that you are unlocking your "rec" handle before you're
done using the unpacked ham. Since the ham struct consists of a few
pointers pointing to different places in your record handle, the handle
needs to remain locked to keep your pointers from becoming invalid. Call
MemHandleUnlock(rec) after displaying the alert and setting the fields'
text.
