Just informing you in hopes that it will help:

I received the error in the title of this post. (I tried to include a clip of the screen here, but it didn't like it.)

Here's the text of the problem details:

I had started a new basic report view. I deleted the output selection group. I made the view larger. I copied one of the buttons (so now there are three). I renamed and resized them. I positioned the left-most and right-most buttons. I wanted to evenly space them left to right on the view so I selected all three buttons and right clicked on them and bang! got this error.

I clicked on "close program". After several minutes it still hadn't closed, so I went into task manager and have been unable close it from there either.

HTH
