The reason that your windows come part way down when driving (with the top up, I'm sure) is that one of the two microswitches in the roof latch receptacle is being released. If you don't want to replace this microswitch (it gets deformed over time) you can resolve this issue by adding a small spacer on the tip of the metal latch so that you are sure that the microswitch remains depressed, even when gong over big bumps.

For the windows going all the way down, check to see if you have moisture or water under the left seat (driver's side in U.S.), near or around the immobiliser that is located there. Also check to see if there is moisture in the foam padding under the carpet behind the seats, especially the left seat. If you do have moisture there, you can remove the immobiliser and take it apart to possibly clean it with isopropyl alcohol. It's important to prevent any corrosion that may result from any moisture in that area.

If you do find moisture or water, you must locate the source of the water intrusion. It usually comes in due to clogged drains in the foam drain trays under the V-levers, and sometimes through the door car, when the seal has not been properly installed after a window regulator replacement. In the latter case, the carpet at the bottom of the door card and below the door sill will be wet.
