Hi,
my experience is that IE has some strange caching behaviour, so my suggestion 
is that you add a random request parameter to the kaptcha img src, e.g. var 
captchaUrl = '/myApp/captchamail.jpg?tmp='+new Date().getTime();

Hello,
I tried the suggestion on comment 6, but I'm still having issues in some 
instances of IE9, someone has another possible solution for this issue?
