Only two problems........
#1.) We're not talking about tabs
#2.) It's something that MS changed from ie7 to ie8
It's easy enough for *me* to add the '-nomerge' to the path, but what about my wife, mother, grandmother???
Read the bolded comments again from the other site. MS are the ones who *wrote* the programs so there's no one else to blame.
Wait, P.S. I'll add one more to all this......
Dunno if it's the same in XP cuz I can't remember, but in my fresh Win7 install, ie8 didn't show the "menu toolbar" by default and I can just imagine a suggestion like, "Hey, just go to File>New session (still twice as many steps as in ie7) and then that person looks all over the screen trying to find the "File" tab" LOL!!
I guess we have something new to hope for in ie9 then, eh? Keep the tabs same-session, but make new windows separate sessions and maybe they can swap to put File>Same Session in the ie9 menu!!
