[galaxy-dev] No Menu after submitting workflow

I'm getting inconsistent behavior when I run a workflow. I have one workflow,that when I run it, the green box indicating my workflow has been submitted shows up in the middle panel with Tools to the left, histories to the right, and menu above. For another workflow, I submit it successfully, but the green box ends up on a page with nothing but the green box. No tools, no history, no menus. Both of these are being done using the same browser session (running firefox on a mac). Thanks, Dave
