Appears folderlist.xml was corrupted, with duplicated entries for each
sub-folder.  I have no useful editing tools on this Windows machine
that I could find, haven't even used Windows since the last millennium
(NT4!), so I had to manually edit the too-large xml file with notepad
to delete the extras.  Works.  Extra folders are gone and no mail
missing that I can see.

Question: is there a way to have claws regenerate a fresh
folderlist.xml when/if needed?  Just deleting the old file does not
work, claws then wants to load the .bak file which was also corrupt. 

Question: this Windows version seems very unstable.  Crashes and shuts
itself down multiple times a day which is something I never experienced
with the linux versions over many many years.  Is this 'normal' with
this version or is there something I should be looking at?
