Mouse does not work after resuming from Standby mode

[Sheri Sourbeck]

I have a laptop loaded with Win2K Pro, SP4. The startup Shell on this
system has been changed from Explorer.exe to a custom application that I
have written. The system has also been configured to go into standby mode
after 30 minutes. When the system returns from standby the mouse no longer
works. If I change my shell back to Explorer.exe I do not experience this
problem.

NOTE: I do not have the option of leaving Explorer.exe as the shell and
placing my application in the starup group. This system is installed
onboard aircraft and the FAA wants to ensure that there is no access to the
OS. Access to TaskMgr.exe has also been disabled.

Seems to me you have a flaw in your custom code. Some process(es?) isn't
waking up, perhaps because it was killed at suspension time. Could be
some slight miscoding at an API. Try checking services' settings, too.

I did try replacing my application with a simple VB app that just displays a
blank form. I encountered the same problem. Since this was not a problem
when I was using Win2K SP2 I suspect that Microsoft has introduced a problem
in either SP3 or SP4.

SP4 has problems for many people. Try SP3. It could also be a Windows
update that included an updated driver for the mouse.

Using SP3 rather than SP4 did resolve the problem. Thanks.
