if units weren't so glitchy

On the first day I bought the membership I was able to easily move units about. Today they won't budge. The page just reloads every time I try to move, lengthen or shorten one. Another unit is shaded to the back, but I don't know why, or how to bring it forward, or open it, again the screen just reloads every time I click on it. I paid for a membership, but I'm seriously considering just plastering my windows with post-it notes just so I can finish my planning.
