Switching from Full screen to windowed

Hi all,I just wanted to know if this happens to others. I usually run FS2002 in full screen mode. When flying the PMDG737 if I switch from full screen to windowed mode, maybe to check ServInfo etc. the plane for like a couple of seconds goes crazy, same when switching back from windowed to full screen. With the PIC767 I used to get the throttles to go to idle and back up when doing these operations.Just wanted to know if anybody else has experienced this.Thanks for any feed-back.Ciao!Bjorn
