Why does animated gif freezes on form submit in Internet Explorer? Are there workarounds?

ha mo, Dave Clark, teccnoraj,


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     The most likely cause of animated gif's freezing is not 
completing an event correctly.  The first rule of thumb is that all 
event handlers should return (ˇonly!) either a true or a false value 
to the event.  To be safe, don't trust the standards which state that 
the return value to an event defaults to true when no value is 
actually returned by the handler.
     In the case of a form submission, it might be the onsubmit event 
which is getting hosed.  Form validation routines should be performed 
as follows:
<form   ...etc...   onsubmit="return FormValidation(this)">
     Then, just make sure that the onsubmit event handler returns 
either a true or a false value.  For example, the following is just a 
skeleton and some psuedo-code for the form validation function 
indicated above:
function FormValidation(f)
{
    if (some error)
    {
        alert('some error message');
        return false;
    }
    return true;
}
Take care,
Dave Clark
