Please provide additional information about the crash here

I was testing out the Projects plugin in my XP workstation at work. It
allowed me to create a folder on my desktop but then when I tried to expand
it I got the following crash.

Checked in a fix for this. There are still some issues with the folder icon not 
being
updated properly afterwards but this can be ignored for now I think.

The error was because the windows tree ctrl doesn't like having 
SetItemHasChildren on
nodes that don't actually have any child nodes. Trying to expand it would cause 
the
exception followed by the tree ctrl being cleared of all nodes.

Fix was to check directory for contents before calling SetItemeHasChildren on
directory node.
