WOSubmitButton IE Explorer bug

i have a WOSubmitButton within a form that doesn't work on Mac or  
Windows IE.  when clicking the button in IE no action is performed.   
however, when i test the app in Safari, Firefox, Mozilla the  
application works as it should.   WOImageButton doesn't seem to work  
in IE either?


is there anything i should be looking for that would stop IE from  
allowing forms to be submitted?  WOConditionals, form names, etc...   
what's really weird is that all the other forms on this page work.   
i'm not using any javascript on this page.

thanks!
