Scrolling problem on Safari

Hi, I wrote the offending code, and I apologize for your troubles. I
just didn't have a Mac to test on. I'll try to help debug it in anyway
I can though.
Here's what's supposed to be happening with those three functions,
reset_click, click_on_list, and use_arrow_keys. Surrounding the message
list is a <div> named mailcontframe. It's this div tag that contains
the scroll bar. What I sought to accomplish is to enable the arrow key
functionality only when the last click was inside that div tag.
It does this by setting the in_message_list flag to true or false
depending on whether the document was clicked or the mailcontframe was
clicked. If the mailcontframe was clicked, it would normally fire both
events because the mailcontframe is part of the document. Because of
this, when the mailcontframeis clicked, it cancel all other pending
events. This *might* be related to your problem.
Here are some tests for you to run to help me diagnose the problem.
1) resize the browser window until you have a vertical browser scroll
bar. Click on anywhere other than the message list and then try to use
your arrows to page through the window. The window should scroll.
2) Do the same thing, but this time click on the message list and use
the arrow keys. The selected message should change and the window
should *not* scroll.
functions to make sure that they're firing when they should be. To sum up:
When you click on the scroll bar or on any message, click_on_list()
When you click elsewhere, reset_click should fire.
These are the first two things I need confirmed.
