The "Drop media file to donate here" button (second screen of the UploadWizard) will sometimes fail to bring up the file dialog (in Chrome; possibly other browsers)
Repro:
- Visit http://commons.wikimedia.org/wiki/Special:UploadWizard
- (optional) check "Skip tutorial"
- Click "Drop media file to donate here"
- (if necessary) Shift-reload and repeat
Eventually, when you click, it won't come up.
