SYMPTOMS
A DDEML client performing frequent Connect/Advise operations alternating
with frequent Unadvise/Disconnects on the same server, topic, or item may
cause the server to leak globally shared memory. The leakage will progress
until there will be insufficient resources to run any applications besides
the server. At this point, the server must be closed to free up memory.
CAUSE
When the client DDEML window is destroyed by a call to DdeDisconnect, there
are still posted messages in the queue to this window, causing this leak.
