This a common problem for many of us. Be VERY careful in using that window. Continued use of it can result in needing a replacement window regulator and even worse, a new window should the plastic tabs break off from the bottom of the glass.
Many of us have used a silicone spray on the window tracks on a regular basis to keep the design defect at bay.
