Open Croquet 1.0 SDK kept on crashing when we tried to connect multiple world. Then I learned from a conversation with Mark McCahill that the fix to the crashing issue is available using Croquet's built-in update mechanism. Here's the step by step instruction of how to get to the update for the connection crash fix:

1. Left click somewhere in the Croquet desktop to open the World menu, and select the "open" item. (for mac, use the normal click)

2. Open a Monticello browser.

3. In the right pane of the Monticello browser, click on the line that says "http://hedgehog.software.umn.edu:8888/Contribution" then click on the "open" button at the top of the Monticello window. A new Monticello window appears listing the categories within that repository.

4. Click on the refresh button, then scroll the left pane of the window and look for a bolded category name. If you have never performed this update, you should see the category "Wisconsin" is bolded. Then click on the category "Wisconsin".

5. You will now see that the right pane has a list of "Wisconsin" packages on the right pane. They look like "Wisconsin-hrs.1XX.mcz". The most recent is at the top of the list and bolded if it is not installed. But you should start upgrade from the lowest BOLD package. Click on it to select it. You may have to wait a little for Croquet to download the package from the network, but once a local copy of the package exists, the "load" and "merge" buttons will be enabled.

6. Close the Contributions repository window, go back to the first Monticello browser window and close it too.

This should fix your crashing upon connection problem in Croquet. Try to apply other updates if you can, it's a good idea to keep your Croquet image up-to-date.
