I've mentioned it before, but I've upgraded the OS and Firefox (2.0.0.12) and it still is somewhat erratic. Clicking on the link works most times, but every now and then it simply 'deselects' the current cell but fails to notify the server. No vertical bar to suggest evaluating, and the cursor disappears. Clicking on the cell restores sanity. I've monitored the network traffic using wireshark (with the server in insecure mode so I can read the messages) and see all the transactions up to the point where I click on the link but nothing comes through at that point. Must be something in the Javascript, I guess, but I haven't been able to figure out what as yet.
