Summary:

PROBLEM ID: WIN9110009

SYMPTOMS

The virtual machine manager (VMM) services Hook_Device_PM_API and

Hook_Device_V86_API should return the address of the previous

handler when they succeed. Under Windows 3.0, these services return

the address passed in, which prevents chaining to the previous

handler.

STATUS

Microsoft has confirmed this to be a problem in Windows version

3.0. We are researching this problem and will post new information

here as it becomes available.
