SYMPTOMS
When you are running a multi-threaded Windows Sockets program using the IPX protocol, Windows 95 may stop responding (hang), or you may receive an error message similar to the following on a blue screen:

An exception 0E has occurred at [segment]:[address] in VxD WSIPX(01) + [offset]. This was called from [segment]:[address] in VxD NWLINK(01) + [offset]. It may be possible to continue normally.

CAUSE
When a multi-threaded Windows Sockets program uses the IPX protocol, a page fault can occur if an invalid pointer to a buffer used by Windows Sockets over IPX is used.

Note that this error occurs only with multi-threaded Windows Sockets programs; it does not occur with single-threaded programs.

This issue is resolved by the following updated file for Windows 95, and later versions of this file:
