Thanks Frank. About the same time you figured it out I fixed mine, not quite as dramatic:
Pulled the drawer all the way out, cleaned and lubed the wheels. Checked the bottom and found dirt and wear spots where bin was rubbing. Cleaned it thoroughly including the wear spots (steel wool or similar would do). Did the same thorough cleaning of the floor of the unit, making sure to get the wear spots rubbed down. Lube the rails, put the door back in, good as new.
I did check the alignment and it looks good. Just the two spots near the front, probably about where you put the screws in.
No more dirty looks here either!
