Comment 1 for bug 1043272

Which version of Unity are you using? Do you have all the available updates installed. in future please use command 'ubuntu-bug unity' to report unity bugs.

About this bug report. I am having hard times understanding the issue that you described. please do attach the screenshot as you mentioned in the description.

My blind guess is what you wanted to describe is that the launcher is not revealing when you hit the left edge.
