Mouse events not captured by proper window

[S Barnes]

The program opens fine, but as I use it certain windows will start permanently capturing the mouse click inputs. If I click on the toolbar that will work, if I then try and use the file open dialog it will not register any mouse clicks, they are instead being passed to the toolbar. I can tell these are still being passed to the toolbar becuase if I double click in the file open dialog the toolbar will minimize as if I had clicked on it. Similarly other windows will permanently capture the mouse inputs if I click on them first (if I first click on the file open dialog the toolbar will not work).

Steps to repeat:
*Launch program
*click on the "toggle crosshairs" button on the toolbar
*select File/Open
*mouse clicks not registered in file open dialog

I downloaded the source code and compiled it myself, this resulted in identical behaviour.
