Lost Ability to Place Breakpoints in VS2010

I just lost the ability to place breakpoints in Visual Studio 2010 by clicking on the side of the designer. The only way I could do this was by using the F9 key. Well after snooping around for a while I found the solution. All you need to do to fix this is to go to Tools>Options, select Text Editor on the TreeView on the left. On the right pane under Display make sure Indicator margin has a check next to it.
