Do Events Run in Threads?

[Tom Frantz]

I'm using IE 6.0 for Windows.

I have a table with several rows where each row has a column that contains
two checkbox controls ("approve" & "reject"). A form (separate from the
table) is submitted each time one of the checkboxes is clicked and the
response is targeted to an <iframe> on the same page. I would like to be
able to prevent the user from clicking another checkbox until after the
response comes back from the form submitted.

I've tried handling this by setting a global variable to true whenever the
form gets submitted, but that doesn't seem to work all of time. If I keep
clicking very quickly I can sneak multiple submissions through. I'm trying
to figure this out and all I can come up with is that perhaps IE (and
perhaps other browsers) run events such as onclick in their own threads?

Is that true? Anyone have a good idea of how to code something that will
prevent another form submission until after the response comes back from the
form?

How about some code? You need to be certain that the flag is inspected and
set prior to allowing .submit() to be called.
