SYMPTOMS
When you use automatic configuration, you may receive a general protection (GP) fault error message. In some cases, you may receive any of the following error messages:

Application error GPF in Urlmon16.dll at XXXX:XXXX

Application error GPF in Compobj.dll at XXXX:XXXX"

This behavior may occur when all of the following conditions exist:


 * You start and quit Internet Explorer several times.
 * Internet Explorer is configured to use a Config.ins file located at an HTTP URL address.
 * Internet Explorer is configured to use a default home Web page at an HTTP URL address.



CAUSE
This behavior occurs because Autoprox.dll does not correctly free resources when you quit 16-bit Internet Explorer. This keeps variables in memory that are not reinitialized the next time you start Internet Explorer. Internet Explorer then uses variables that were valid during the last session, but now cause GP faults.



RESOLUTION
A supported fix that corrects this problem is now available from Microsoft, but has not been fully regression tested and should be applied only to systems experiencing this specific problem.

The English version of this fix should have the following file attributes or later:   File name      Size           Date --  Autoprox.dll   41,984 bytes   09/17/98
