4 Window Automatic Rolldown

Has anyone ever accidently rolled down all 4 windows on their I35 by remote? I did this one time during a rainstorm. It took me by surprise and I had to jump back in the car and insert the key in the ignition just so I could roll them all back up. I still don't know how I did it. Any ideas?

Howdy,
My 96 I30t does the same thing when I hold the unlock remote button down fro approx 4 secs.
1 click is driver door unlock, 2nd click is all doors unlock, constant pressure for 4 secs and front windows roll down.
Hope that is it.

Thanks Micano,
I'll try that and see if it works.
