This problem appears mostly on the "template categorization" hits but I have seen it on a few others. There is an Amazon Turk bar at the bottom of the screen. It is not fixed but is at the bottom of the scrolling window. It covers 90% of the submit button. I am able to select the button by clicking on the top edge that shows. Is there a fix for this? Resizing the window does not seem to work.
That is annoying. I've experienced this. There is a fix for that. In the Mturk suite, click on the icon on top right of your browser. MTS. Then click on MTS options. On the top - Enable Scripts, you'll see Workspace Expander. If it's checked, uncheck it. That should fix it.
