wmi issue

Hello

I currently developing an vb.net windows service application that
contains a class "WMIcollector" that enables the retrieval of
win32_product, feature, elements, ... through WMI.. I got something
weird going on when retrieving Win32_SoftwareFeatureSoftwareelements.
For some reason the collection of
win32_softwarefeaturesoftwareelements causes some
annoying floppy drive access. I copied the class "WMIcollector" into
a windows form application project where the problem of the floppy
access strangely enough doesn't occure...

Its certainly not the windows service application itself that access
the drive. It just uses the WMIcollector class. When the service is
interrupted and stopped, the floppy drive is still active. So i think
its wmiprvse.exe service that uses the drive.

I already searched in newsgroups and found there was some bug in wmi
in earlier versions of
windows and wmi (windows 98 & 2000). The collection happens on a
windows xp sp2 machine and didn't find anything what may cause the
floppy drive access.

Anyone an idea what the cause may be and maybe solved it? Or has an
idea when unwanted floppy access may occure when using wmi?

thanks on advance

MyCollection = searcher.Get()
