Hi,
We tried your new slick upload version "SlickUpload-6.1.7" but it seems it is not providing multiple file select support for Internet explorer, So we are using flash component for selecting multiple file and posting to server and in background slick upload component is handling "maximul file size" limit and file storage, but now when we are tring to implement navigation message with below javascript code then it is showing multiple alert messages for navigation and page get hanged.
window.onbeforeunload = function ShowConfirmationMsg()
{
if (isUploadInProgress == 1 )
{
return "Your presentation(s) upload is still in progress and will be lost if you navigate away from this page.";
}
}
Please let us know the workaround to solve this problem.
