Odd window glitch.
 

Hi guys,
Now have put 600 miles behind the beater Boxster, still driving great.
However this morning it was below freezing, I stopped by a convenience store to grab something on the way to work, left the engine running to let it continue to warm up, and when I came out the driver's window was halfway down.
I raised it back up and have had no issue the rest of the day.
Anyone else have this happen? It's almost like it went into some default mode for a sec.
Thanks in advance.
