The information in this article applies to:

Microsoft Win32s, versions 1.1, 1.15, 1.2, 1.3, 1.30c

SYMPTOMS

The Windows local reboot feature (CTRL+ALT+DEL) should terminate a hung application. However, if the application is a Win32-based application, using CTRL+ALT+DEL exits Windows.

CAUSE

This is a limitation of Win32s. When the VxD that handles hung applications tries to access the application stack, it uses ss:sp, instead of ss:esp, as if the application were a 16-bit application. This causes the VxD to crash, and when the VxD crashes, the whole system terminates.

STATUS

This behavior is by design.
