I did go back and yes, Notepad successfully launched. :)

So I then replaced Notepad.exe with the location of the 64-bit Process Explorer:

• "D:\SOFTWARE\WINDOWS SYSINTERNALS\PROCESS EXPLORER\PROCEXP64.EXE"

and that worked perfectly by holding Ctrl and left-clicking  the taskbar!

If I were to set 'Double click on empty space' in 7+ Taskbar Tweaker = Nothing (default)

and change the entry you had me create from:

emptyspace|ctrl+lclick   to   emptyspace|ldblclick

that should work as the replacement for opening Process Explorer instead of Task Manager?

So adding a Mouse Button Control advanced option would override the 'double click on empty space = Nothing' in the main interface? This shouldn't cause any conflicts?

Thanks RaMMicHaeL! Much appreciated. :)

Back again RaMMicHaeL,

I have tried to implement this using your example, but I have stumbled to do this - I'm not sure what I'm doing wrong. I have added an entry in the Advanced Options in the Mouse Button Control section, using:

• Name: ctrl+shift+lclick
• Data: 1000

For some reason, when I go to edit the registry in regedit, I see an entry is created under Mouse Button Control key, but is a DWORD value. When I go down to the Strings key, I don't see an entry there.

Do I need to create a new String value in the Strings key to match the above Name/Data?

Once that value is created I was then going to substitute the '1000' with the location of 'Process Explorer' as a portable application. e.g.:

• "D:\SOFTWARE\WINDOWS SYSINTERNALS\PROCESS EXPLORER\PROCEXP.EXE"

^ this was me responding... forgot to login *blushes*. thanks again!
