In theory the VM used when double-clicking on an image or a change set  
is a result of how the mac determines which application to use when  
there are duplicates at the signature level. 'FAST' is the signature  
used by Squeak.

In general the application used must have the largest version number,  
an internally assigned number that I typically increment for each VM  
distributed. In case of version number duplication then the application  
with the latest creation date is used, if duplication then it's usually  
the one you've last moved within the finder.  Ah, os-x might have some  
different opinions here.  Now in the 3.0.x series of VM there was some  
VM distributed that have version numbers out of sequence, so if you've  
got lots of them about then it's possible an older VM might launch  
because of a mistake on my part, although I think if you have a 3.2.x  
VM this shouldn't be a problem. For example double-clicking on an image  
on my powerbook launches a beta test VM I compiled yesterday, on  
another office machine of mine used for testing which contains 37 some  
VM of various forms (many not distributed to the public) causes 3.2.8b5  
to run because that's the latest.

If you have plugins you should also ensure the plugins you are using  
are what you expect. Check with the file server to see if you've the  
latest for your VM and you aren't using a plugin that is now builtin or  
obsolete.

To ensure that you get the VM you expect to run you could use Sherlock  
and find all applications of type FAST

IE do a custom search for file type is APPL and creator is 'FAST'

Then delete the ones you don't want to use. In general older images  
should work with 3.2.8b5, if not there should be a problem we should  
fix. As noted people who collect VMs for a living seem to do the drag  
and drop invocations just to be sure what they run is what they expect.
