Notepad behaves differently in Win 7 versus XP3

In XP3 I could select an entire string of unbroken (no spaces) characters in Notepad by double-clicking anywhere in the string. For example, if I double-clicked anywhere in a phone number written as 888-555-1212, Notepad in XP3 would select the entire string of characters.

However, Notepad in Win 7 sees a dash or hyphen as a space, and double-clicking the string selects only those characters up to the dash.

Is there a way to make Notepad in Win 7 treat a dash as any other character? Or do I need to get a copy of the older Notepad app to replace the newer one?

If only all of life's problems were this small and insignificant. But it's like a dripping faucet that hurts no one but bothers you nonetheless.

I just tested your statement in XP SP3, Win 7 Pro and Win 8 Pro. All behaved identically, treating hyphens the same as spaces.

EDIT - scrub that - so many windows open of networked systems and VMs I confused myself as to which one I was typing in You are right of course, 7 is different.
