Just for the record.

The problem turned out to be unrelated to Norton. It has to do with the
Windows 9x resource limitation for System and User Resources. I only
found this out by chance as I had some other programs running on my
Win98 test machine when I run one of the tests to recreate this users
problem.

My application is written in Python/wxPython and during the start of the
application when the wx.Panels are created Windows 9x just keeps on
eating up resources. The error messages can be just about anything, in
one case it can't get the database file in another it can't create a
combobox etc etc.

Only when I start the Microsoft Resource Meter
(Start/Programs/Accessories/System Tools) did Windows give a sensible
warning message that system is running out of resources and strangly
enough in some cases running this tool meant that the application
actually started up and worked correctly!

I haven't found a clean solution, the current work around is to call the
garbabe collection and display a progress dialog. The dialog is needed
to force Windows 98 to actually return some unused resources. With this
trick my test machine stays between 50 and 70% free System/User resources.

See you
Werner
