AJAX Update Panel problem with IE6

On my site I have an asp:dropdownlist next to an asp:image. Ive put both of these within an asp:updatepanel. When the selected item in the dropdownlist is changed the panel updates with a new image depending on the selected item. This all works fine on FireFox and IE7, however on IE6 I get the following error:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12019

As a temporary fix I have removed the updatepanel tag meaning the page now reloads every time and it works fine. However it would be much better if this didn't have to happen. Has anyone seen this error before, and if so how can I stop it from happening. Why does it happen on only IE6?

Thanks,

Curt.

Two last replies are specially interesting Wink


Thanks for the link bsevo.

I have been testing the site using IE6 on an OS which also has IE7 so maybe thats why its not working? I'll have to try and find an OS which has the 'real' IE6.
