I'm experiencing some strange behavior with my PF3, which started not too long ago. When PF3 ATC talks to my aircraft, I've noticed that the Windows taskbar locks up temporarily, at least until PF3 is finished talking. So if I'm in the middle of doing something and P3D is running in the background, and PF3 says something like perhaps gives me clearance to final on approach, I can't switch tasks to P3D because Windows itself locks up until PF3 finishes its sentence. This is mostly an issue on approach when I'm nearing my destination, and P3D and other apps on my computer are fine - it's just task switching and Windows that locks up.
It happened after I reinstalled a motherboard. So, thinking it was an issue with that, I decided to reinstall Windows and reinstall P3D and PF3. Still, the issues persist. Often, these lock ups are associated with a spike in CPU usage, but while I am overclocking my CPU, I would expect the whole computer, including and especially P3D, to also lag or freeze temporarily while PF3 is talking is this is really a CPU overclocking issue. However, it's only Windows that locks up. All other applications continue running normally and the problem only becomes salient if I happen to try to switch tasks while PF3 is talking; otherwise, I don't notice the issue as my applications themselves are unaffected. Any advice?
