Unsuccessful query freezes form

[ryan]

I have a form that can be used to either set up a new account or update
a current one. There is a field where you enter the name of the
account. There is a button next to it to query the database if you are
updating. The problem is that if you don't enter a valid account name,
the form sort of freezes with blank text boxes and you can't enter any
info. As you can imagine this is a major problem since everyone
misspells at one time or another.

For reference, the textbox where you enter the account name is linked
to the account name field in the datafields. When the query button is
called, I use JS to get the text out of that field and place it into
the corresponding account name query field. Then I call the Query
function.

Any ideas what might be happening here?

Thanks,
Ryan
