Yes it does.

Turnpike is a email client. From it's web site

"The biggest change to Turnpike Six is its look and feel. A radical
departure from previous versions sees Turnpike integrated in Windows
Explorer. This means that your Turnpike folders now appear in the
Windows Explorer folder tree alongside My Computer, Network
Neighbourhood and the Recycle Bin, instead of appearing within a
separate application."

I also have WS_FTP on my machine which interacts with Explorer in a
similar way, appearing in the left hand pane of an explorer window below
all the drives.

I've just installed the new version of TortoiseCVS, ver 0.50. Apart from
TortoiseCVS thinking ALL my files under CVS were Changed (I assume
because of something to do with British Summer Time and the way NT
timestamps the files), every thing is still working as before :-),
including the

Proxy Desktop: explorer.exe - Application Error
The instruction at "0x66819b0e" referenced memory at "0x00d00590". The
memory could not be "read".

on closing explorer :-(

The referenced memory has changed from "0x008f0598" to "0x00d00590" now
but that, I expect, is because I've put two more memory sticks into the
machine recently, taking total RAM from 128MB to 384MB.

I just re-booted, with nothing automatically starting except for the
basic services, and then start explorer, and on closing the error still
occurs.


If you can tell me where I should be looking to find out what's causing
the crash I more than willing to experiment. Just Windows programing
isn't quite my thing, most of my experience is in PHP and MySQL.

Er, yep, bad solution. Actually I think my next machine is going to be
an Apple Powerbook running OS X. Does TortoiseCVS work under WinNT on
Virtual PC on Mac OS X ? <grin>
