I created a menu that pops up a certain target is clicked. The menu
remains visible until the user clicks a selection from the menu, or
moves the mouse away from the menu - implimented with onmouseleave. It
works swimmingly - almost. I messed with it for a long time because I
was so happy to see it work. (I love Mochikit.Signal - great job Bob!)
Then I happened to do something just right to make it break. If I move
the mouse pointer down off the bottom of the div - I can occasionally
get this error:

node.tagName has no properties  -  DOM.js (line 343)

That's right. I said Occasionally. It behaves differently on different
runs. Sometimes it works. Sometimes it errors. That is making it very
hard for me to debug. The menu is a div with each menu item being a div
nested inside it. The outer div has the onleave signal set to hide the
menu. Each menu element has an onclick signal set to make the
selection, then hide.

I am using Mochikit 1.4 and Firefox on Linux. All events are handled
with Mochikit.Signal. I know 1.4 hasn't been 'released' yet. Perhaps
this is still being worked out. Perhaps I did something wrong.

I can post relevant source if necessary, but its long, spread over
several files.

Any help would be appreciated.

Warren
