Projects duplicated each time they're closed/opened

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Define a dynamic (regexp) working set which resolves to some projects
2. Open and/or close one project in dynamic set
3. Observe the project being listed multiple times

What is the expected output? What do you see instead?
Each project should be listed once

What version of the product are you using? On what operating system?
Automated Working Sets 2.1.2 on Eclipse Helios 3.6 / Arch Linux 64 bit

Please provide any additional information below.
Very useful plugin, Thanks!

Glad you like it! I've found it rather useful ;)

So far I can't recreate it. I'm running windows, but I don't think that should 
make a difference). I can close/open projects and still only see them once.

Do you see them listed more than once in the same working set, or in different 
working sets? Are you using the "Top-Level Elements->Working Sets" setting or 
"Top-Level Elements->Projects" setting?

Some more info:
Top-Level Elements->Working Sets
Working Set Label=Site - drupal*
Project Name Regexp=Site - drupal.*
There are about 20+ project that match this description.
Let me know if you need more info
Cheers

Hi! I still cannot recreate it. I'll see if I can try it on a linux box at some 
point, but it may be a bit before I can find one (know of any pre-setup vmware 
VMs that I can download for a quick try?)

Where do the duplicates show up? In the same working set? Across different 
working sets?

Do you have more than one dynamic working set defined?

I have more than one dynamic working set indeed.
Duplicate appear in the same working set.

Actually I just realized this is only happening in the PHP Explorer view (part 
of Eclipse PDT). I can't see this happening on Eclipse Project Explorer.
So this may be a PDT bug...
