Image Uploader 5.1 Freezing on Firefox Version 2.0.0.14 on Vista OS

Hi,

We are using the image uploader on a client's website. It works on all versions (IE, Apple Mac and Firefox). It also works on IE on the Vista OS. However the firefox version freezes on Vista when the aspx page is opened with the control on it. I have upgraded to version 5.1. Here is my code:

iu.activeXControlEnabled = true;
iu.activeXControlCodeBase = ""../Member/ImageUploader5.cab"";
iu.activeXControlVersion = ""5,1,0,0"";
iu.javaAppletEnabled = true;
iu.javaAppletVersion=""5,1,0,0"";
iu.javaAppletCodeBase=""./"";

Is this a known bug or am I missing a parameter?

Regards,
