When I try to upload an image to a thread, I used to be able to use this screen:
Name:  Screen Shot 2014-05-13 at 10.54.30 AM.png
Views: 32
Size:  16.3 KB

and click on the "Select Files" button on the bottom. It would open my finder window (Mac OS) and I could search for whatever pics I wanted to put in the post. For about the last six months, however, it often doesn't do anything when I click the "Select Files" button and I have to use the "Basic Uploader." If I click around on some other things, sometimes it will start to work, but 90% of the time, it doesn't work every time .

Any ideas? Could it be a browser setting?
