SYMPTOMS
========

When Windows is running in one of its protected modes, the value returned by the
GlobalCompact() API does not accurately reflect the amount of free memory
available in the system.

In enhanced mode, Windows can swap memory objects to disk. This process takes a
long time relative to accessing an object in memory. Therefore, GlobalCompact()
returns the amount of memory available without performing any paging.

In standard mode, GlobalCompact() never reports more than 1 megabyte (MB) of
memory free because of a memory allocation limit on the 80286 chip.

STATUS
======

Microsoft has confirmed that this problem occurs in Windows versions 3.0 and
3.1. We are researching this problem and will post new information here as it
becomes available.
