flow browser bug

I guess this is known as it's so obvious but anyway..

I used the flow browser to see my stream and the stream i am flowing with.

I right clicked on the browser and selected "hide repository workspaces" the repository disappeared, Then i right clicked again and the little dot isn't there so i cannot show the repository workspace again with our restarting the flow browser.

Same thing with "hide stream" button. It works with the "show repository workspace owners" and "show repository workspace names".

known bug?
