hehehe 'The willies', very british, say it all the time ;)
the button I'm talking about is the upload button which is under the top section "upload from my computer". I click 'Add resources' and it opens the Iframe window. Then for a second I have a button that says 'upload' in this top section, but then it disappears. I can then select a folder to import from using the drop down in the bottom section so it loads the files in that folder and makes a second 'import' button appear (which works fine), then I go back to the dropdown default option of "--Select a folder--" and the upload button above appears again, but does nothing when clicked on.
If I then close the popup and open it again, the upload button does not appear at all, not even for a few seconds, but selecting a folder and then going back to the "--Select a folder--" will still make it appear, but it still wont do anything.
