SYMPTOMS
========
When an application calls the GlobalPageLock() function specifying the handle to
a block of memory that has been fixed in place by the GlobalFix() function, the
address of the memory block can change.
STATUS
======
Microsoft has confirmed this to be a bug in Windows version 3.1. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
MORE INFORMATION
================
The following steps demonstrate this problem:
1. Allocate a block of movable memory using the GlobalAlloc() function.
2. Fix the address of the memory block using the GlobalFix() function.
3. Increment the memory block's page-lock count using the GlobalPageLock()
function.
The address of the memory block should not change between step 2 and step 3
above.
