Bug Description

Binary package hint: unity

Assuming default icon placements in the Launcher, attempted mouse-overs of the above mentioned UI elements in Firefox will reliably bring up the Launcher and execute the home folder in Nautilus or the Trash bin.

For me, it takes a conscious effort to avoid this and even then, it still happens 90% of the time.

This occurs because mousing over Back or Close Find takes a fair amount of deceleration in an area where the outer limits of the button meet the screen edge where mousing over would bring up the Launcher.

Of course, this can be avoided by using the keyboard (Alt+Left, Ctrl+F and then Esc, etc), but it's not a workable solution since it is not user apparent.

I envision two solutions to this bug

1. Increasing the amount of time mousing over to bring up the Launcher by a few milliseconds across the board
2. Add an if statement to the Launcher code that prevents the Launcher from being invoked for a few extra milliseconds if a mouse-over event in an application has occurred within the past few milliseconds.
