Toolbar I want to be visible in 1 application only, is visible in all other

[Dale]

I have created a toolbar that I want to use with notepad++ only.
Its trigger is - 
!a"D:\Thepad.txt - Notepad++" "Notepad++" "" "" "" 0x2 /NOTEPAD++,NOTEPAD++PORTABLE

The item properties pic is here - pic

I want it to be visible only when the active widow on screen is notepad++ (notepad++ portable I am using). But the problem is that once I start this toolbar by going to the my made toolbarmacro in quickacros application, the toolbar then appears in all the applications.So it is visible in all the applications which is a nuisacne as I want it to be visible only i notepad++, and not when any other application windows are active.

How can I make the toolbar visble only in notepad++?

Thanks.
