ah, so I created a loop from audio with help of loop construction, I turned it into a groove clip loop.....when dragged out, I cant see any of those indentations, marking to show where the start and end points of the loops are?????anyone

Possibly you didn't complete the task of making it a groove clip ?
When your in loop construction you save the loops by clicking on Save in the loop construction window.
 
Have you tried dragging the loop out to see if it repeats ?
You have to drag and let go to see the repeats. Sometimes you cant see the repeats(loop) until you let go of the mouse button.

Thanx chuck, all good, it was a bug or something, I closed sonar and opened it again and the groove clips are good now.......Yeah, weird......The top and bottom of the groove clips were literally an endless line with no indication of start and ending points.....it really doesn't help my confusion, when the computer gets confused!!!

Glad its all sorted man.
