Solution to my PIC sound problem

Hello,some days ago I asked if someone knows the problem about some missing PIC-sounds (A/P-disconnect, A/T-disconnect, altitude warning).Now it seems I found a solution:The sounds disappear after any panel resizing. I used to start FS2002 in window mode, then switched to fullscreen -> sounds are gone.After starting direct in fullscreen mode, everything is ok.If I need to switch to another application I use Ctrl-Tab.Matthias Huck
