The version that I’m running is: CuteWebUI.Ajaxuploader 3.0.20090518

 what seems to be the same that the latest download from the site is, however, after downloading the latest version and running it the Framework 2.0-VB-MicrosoftAjax version if it, the upload button still disable in Firefox, the page seems to be waiting for a while from the host and then the button never seems to became enable.

This is causing major problems, we bought the license recently and the control is currently running in a production environment, we have received several complain from user being unable to upload files from Firefox, I’m really lost at this point since I have no clue where to look to fix this problem. Any help would be greatly appreciated
