Narrative:
We were cleared on the clare RNAV departure out of dfw off of runway 17R. We thoroughly reviewed each fix. Then the controller cleared us directly to clare. We executed and went there. Well past clare; the center queried us as to if we were given a vector from departure. He said that we had flown through the SID. What apparently happened is that when we executed direct clare; tekbe dropped out of the SID. We had clare; poten; and direct swb in our FMC. He immediately turned us back to tekbe (a 080 degree heading) and indicating that 'this was happening a lot with air carrier X.' (I may add that this was a pegasus airplane; which in my opinion is a far less reliable and much more difficult FMC to work with than the other.) he didn't indicate any other problems. In retrospect; I will always rechk that points a the SID after the point that I was cleared to.

Title: FLT CREW OF B757-200 EXPERIENCE A TRACK DEV ON TRANSITION PORTION OF CLARE RNAV SID FROM DFW.
Narrative: WE WERE CLRED ON THE CLARE RNAV DEP OUT OF DFW OFF OF RWY 17R. WE THOROUGHLY REVIEWED EACH FIX. THEN THE CTLR CLRED US DIRECTLY TO CLARE. WE EXECUTED AND WENT THERE. WELL PAST CLARE; THE CTR QUERIED US AS TO IF WE WERE GIVEN A VECTOR FROM DEP. HE SAID THAT WE HAD FLOWN THROUGH THE SID. WHAT APPARENTLY HAPPENED IS THAT WHEN WE EXECUTED DIRECT CLARE; TEKBE DROPPED OUT OF THE SID. WE HAD CLARE; POTEN; AND DIRECT SWB IN OUR FMC. HE IMMEDIATELY TURNED US BACK TO TEKBE (A 080 DEG HDG) AND INDICATING THAT 'THIS WAS HAPPENING A LOT WITH ACR X.' (I MAY ADD THAT THIS WAS A PEGASUS AIRPLANE; WHICH IN MY OPINION IS A FAR LESS RELIABLE AND MUCH MORE DIFFICULT FMC TO WORK WITH THAN THE OTHER.) HE DIDN'T INDICATE ANY OTHER PROBLEMS. IN RETROSPECT; I WILL ALWAYS RECHK THAT POINTS A THE SID AFTER THE POINT THAT I WAS CLRED TO.
