If you have AjaxUploader in a modal dialog the multiselect is not working. It works perfect in Google Chrome, Safari and IE.
Is this a known problem? If the dialog is not modal, then FF is working. Now I use a "dirty" work around in page load:
detectFireFox = LCase(Left(Request.Browser.Type, 7))
If detectFireFox = "firefox" Then
DialogFileUpload.Modal = False
End If
Is there at a better way to solve this?
