OK, I've tested this on my Mac with a freshly downloaded Firefox 3.6.8.
No such problem.
Phil, it looks to me like it might be a bad early version of 3.6.8.
Mac users -- we need you to try this on Firefox 3.6.8:
1. load http://www.saintmarys.edu/~pbays/JStest/HTMLFiles/NT1.html
2. click on the link under the applet to display chlorophyl
3. close the browser
4. open the browser
5 repeat steps 1 and 2.
Phil's experience is that in step 5 the click will not work.
My experience is that it will work.
Please report EXACT Firefox version.
Bob
