Changong Up - Its Happening Again

I have a Claud Butler with a 7 speed cassette and Shimano Acera rear derailleur, and I have had this problem before so have followed the expert advice but this time its still not working; to recap....
I have a problem changing up (from a lower to high gear), if I am in bottom (biggest gear) and want to change up 1 to 2, nothing happens. If I change again 2 to 3 the derailleur will then change to gear 2 while the control shows 3.
This happens all the way up so that when the control says 7 the gears are in 6, after a couple of rotations the chain will move to 7. However changing down 7 to 6 to 5 etc works perfectly.
Things I have done:
Cleaned and re-oiled the chain
Cleaned and lightly oiled the derailleur
Cleaned the cassette
Replaced the inner and outer cables.

when shifting 7 to 1 it is the cable pulling the mech. when it 1 to 7 it is the mech pulling the cable.
the problem you have is friction.
dirt cables. too tight bends or just poor cable routing."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Hi Nicklouse
Yes, when shifting 7 to 1 it is pulling the mech.
I also thought friction, that is why I replaced the inner and outer cables and checked the bends and routing - no problems there.0
