I've got a sometimes very large radioButtonList which is being decorated with FormDecorator.

For some reason yesterday in IE7 when I click on a different item, it takes up to 3-4 minutes to change the selected index. This doesn't happen in Firefox. It also doesn't happen on my collegue's computer - I'm running Vista 32bit, he's running XP. The only other Vista computer in our office also has the problem.

I know that its not code-related, as I hadn't changed any code when this started happening. To be sure of it, I reverted my code to an older version, and also checked our test site which hadn't been updated in some time.

I also thought it might be a conflict with some Windows updates as my computer installed 27 of them yesterday. However, after uninstalling them all (one at a time) when I rebooted they got reinstalled anyway. *grr*

It only appears to be an issue when the radioButtonList has a lot of items in it. Also, when I remove the FormDecorator, it works as normal, even for a very large list.

Is anybody else experiencing this? Any suggestions on what is causing it?

Hi John,

So far we have not been contacted with such a problem. You do not specify the size of the RadioButtonList - are we talking about tens of items, or 100+ items? Is it possible to open a support ticket and send us the page for us to examine?

Best wishes,
