Bug Fixes for App

I have a few bugs in a Mac menubar app that I have, under OS X Mountain Lion. When the app window is pressed many times, it crashes, and causes the computer to restart almost every app. During this, the screen applies a light blue tint to the screen briefly. It is a note taking app, for those wondering. The app also uses the BWToolKit. I want it removed, but the interface to remain looking the exact same way via images. Do not bid more then $60, and there must be no milestone. Thank you!
