Mea culpa.  Meant to send this to the list, not just Eric.

I use bzr-explore on Win7 almost every day for about a year.  I launch
bzrw.exe within the Windows Explorer desktop GUI (not Cygwin), as installed
by the standalone installer for bzr.  I have yet to have any crashes
attributable to Win7.  Bzr explorer does, howevere, take a long time to so
some operations on "large" branches (10K+ files amounting to a few GB).  I
note that bzr 2.2 brought many improvements in speed.  But if you see bzr
explorer crashing on Win7 for small test projects, then there might be a
real issue.
