Bob, thanks for replying. I found the solution elsewhere - here it is:
To try and find if a 3rd party shell extension is causing your Windows
Explorer to crash on certain actions, you'll need to download this handy
(and free) utility: ShelExView
(
http://www.snapfiles.com/get/shellexview.html). It will let you view &
disable shell extensions.
After you downloaded & executed it, ShelExView will show all shell
extensions installed on your system. You could sort the entries so that
you'll have all non shell extensions grouped together. Next, select all
these non Microsoft shell extensions, and disable them. Try the sequence
that would previously have resulted in Windows Explorer crashing (for
example browsing a folder, or right-clicking a file). If no crash
occurred, one of the shell extensions you disabled has been causing the
crash. To find out which one, start enabling one shell extension at a
time, each time testing to make sure you can still use Windows Explorer
without it crashing, until you find the shell extension that would cause
Windows Explorer to crash.
ShelExView gives you all additional information you need to know such
as the product & company name of the shell extension, as well as the
version number. If you would like to continue using the of the 3rd
party whose shell extension is causing the Explorer crash, contact the
company responsible, and check to see if there is an updated version of
the software you are trying to use.
