Is My Window Regulator Ready to Go?

[Juanted]

So, am I driving on of NJ's famously bumpy roads yesterday, my driver's side window decides to roll down by itself. I rolled it back up, and it has not happened again. I know one saying around here is that "You're not a true X5 owner until you've had the window regulator go out." Is that a sign that my regulator is about to go on the fritz? I know many of you have experienced this. So, is this a sign? Is this how it starts? Or... could a bump on the road cause this? When the regulator goes out, does it do it constantly, or intermittently?

thanks, guysl
