cannot select region using mouse

i made and exported recording on mac, but did not close project after export. now i tried to select a region using mouse and left click. i drag right to desired point (0.0>4.0 seconds) and timeline arrow stretches to 4 seconds but when i let go of left click, the timeline arrow stretches entire length of recording and the section i wanted is not highlighted. recording also begins to play the moment i let go of left click.

any help is greatly appreciated.

It sounds like you are dragging in the timeline (which will start playback) instead of in the waveform.
