Issue with Spaces - Snow Leopard

My issue is with Spaces. Here's the issue outlined in a situation that happens often:

- I have Photoshop allocated to Space 2 and Illustrator to Space 3.
- Let's say both apps are open with a file open in their respective Space.

In Leopard, if I were to double click on a Photoshop file from a Finder window in Space 1, I would be immediately taken to Space 2, where Photoshop resides, and the file would open -- everybody's happy.
However in Snow Leopard, the file opens in Space 1, so I'd have a Photoshop file open in Spaces 1 and 2. I cannot drag the file from Space 1 to Space 2. If I try, I'm zipped over to Space 2 and then immediately zipped back to Space 1. Very frustrating and happening with files regardless of the application/assigned Space.

There was another topic I found where someone describes the exact issue I'm having, but it doesn't seem this person found a fix and I too have yet to find a fix for it.
The issue I'm having is described by this person as the second problem outlined in the original post in this thread - http://discussions.apple.com/message.jspa?messageID=10122332

Can anyone help?
