Take Bmaj7; and learn 2 versions of it. 1 rooted off of the 'E' string and one off of the 'A' string. (When I say 'learn' I mean just remember the shape, OK?) Now follow these steps...

PART 1
1)Finger the chord at the 1st fret
2)strum the chord 1x
3)Take your fingers completely off of the fretboard
4)Move up a fret, and repeat these steps until you hit the 12th fret (or so) with your first finger.

PART 2
1)Finger the chord at the 1st fret
2)strum the chord 1x
3)Move the chord up to the 2nd fret
5)strum the chord 1x
6)Move the chord BACK to the 1st fret
7)strum the chord 1x
8)Move the chord up to the 3rd fret
9)repeat this, always coming back to the 1st fret so it's like this;
1st - 2nd 1st - 3rd 1st - 3rd 1st - 4th 1st - 5th etc until you get to the 12th

PART 3
Drill this chord with 4 other chords that are VERY easy, play each chord only 1x, and do each one for a timed interval (1min each!)
Remember that you just want to work on getting the dead time between the transitions down... Since you have 2 fingerings of Bmaj7, I'd do this drill 2x, once with each fingering. Some of these pairs will sound better than others, keep in mind that this is an exercise to help you really learn the PHYSICAL part of playing these chords. Once you're done, go improvise,or work on a tune that has this chord in it...

Run these drills 2x a day for a week and I bet you have the fingering of Bmaj7 mastered.

Hope that helps, good luck!

that totaly helps thanks alot

Practice is the key. Previous commentor's reply is spot on. The only thing to add would be to practice all of the moveable chord shapes all over the fretboard and always practice clean...no noise. Good luck! TK

ditto. If you find your hand cramping up heaps (I used to have this problem) try relaxing your hand as much as possible whilst playing.
