I'm using Plupload (jQuery version) with HTML4 for IE, and for some reason it's not opening the File Dialog when I press the Add Files button.
The Plupload container is placed in a dialog, and I call .pluploadQueue() just before I show the dialog, each time.
It works fine on FF and Chrome.
The Cause
I call
.pluploadQueue()just before I show the dialog, each time.
The Solution
Apparently, Plupload doesent seem to fire the dialog if the Plupload container is hidden (display:none) while evaluating .pluploadQueue()
I had to do a display:block before calling .pluploadQueue() - since I didnt want to fade in my dialog till after the Plupload stuff was done, I simply set the containers opacity:0
Long story short: Make sure your Plupload container is not hidden when you call .pluploadQueue()
After showing or moving the button, call uploader.refresh() to have the runtime shim update its position.
