Expected behaviour:

When I click an attach file button, a file browser window should open showing files on my local system. When I select a file, that file gets uploaded through the browser.

Actual behaviour:

When I click an attach file button, the cursor changes to a colourful spinny wheel, and no file browser window opens.
