Thanks for the info !!!
I saw that link before from a search on "power windows" but I didn't know if that was the only window problem.
FYI - I called a local Isuzu dealer (Bowser in Pittsburgh) and the service guy was very helpful. He said he hasn't seen that problem personally on the 3 or 3 VX's that come into his shop, but he said I'm probably looking at $105 for labor + parts if any are needed.
Hopefully I'll be a VXer by the end of the day today!
