Cah155,
That sounds symptomatic to a dying power window motor. I endured about 2 years of contending with a sluggish window motor in my Insight but I finally replaced it this past weekend.
I would recommend testing the motor before replacing it, however. Here is the procedure for testing the power window motor on a '00 Insight:
1) Remove the door panel with as little bending as possible to prevent creasing or breaking it:

2) Disconnect the 4-pin connector (A) from the window motor.

**Shown here: 4-pin connector (A)**
3) Test the motor in each direction by connecting battery power and ground according to the table. When the motor stops running, disconnect one lead immediately.
4) If the motor does not run or fails to run smoothly, replace it.

-Pulsar Test-
1) Connect the test leads of an analog ohmmeter to the No. 3 and No. 4 terminals.
2) Run the motor by connecting power and ground to the No. 1 and No. 2 terminals. The ohmmeter needle should move back and forth alternately.
3) If it does not, replace the power window motor.
