Sherm,

Maybe Manfred himself could give you some tips. Or you might want to ask the friendly folks at AIG or MAIW on how to do this?

If your CPU is indeed running at 3.5 GHz, you might consider overclocking it. Also you could go here: https://www.prepar3d.com/SDKv5/prepar3d/getting_help/advanced_configuration.html and here: https://simmershome.de/prepare3d-v5-einstellungen/ (this site is in German, there is an English-language op...

I have never seen this on my own v. 5.4 installation, even with a lot of add-on scenery, photoscenery and AI aircraft with their AI flight plans.

Is your 5.4 installed on a mechanical hard drive, and what are your system specifications?

Jorgen

Maybe the textures discussed in this thread may help?

It would seem that any and all development on v. 5 ceased when v. 6 came out.

On their website, they list it as compatible.

Very odd. I searched my C: drive and found 14 instances of simconnect.dll, so why they cannot find it is kind of a mystery. I also earched for "Virtual Avionics" and found these 2 contact addresses: sales@virtualavionics.com.br contact@virtualavionics.com.br I would send a nastygram to bot...

If Sabre's tip does not help, then try to remember what happened on your computer between when P3D worked fine and now when it exhibits this open/close behavior. More specifically, did you install or modify something?

The mention of possible heating issues brings this up: If the computer is question is a laptop, make sure its ventilation openings are not dusty or even clogged with dust, and make sure it is positioned so it can get rid of the warm air from the exhaust. If this is a desktop, then most likely it is ...

There are so many things that can go wrong with complicated software and add-ons like these, that I sometimes think it's a wonder that anything works at all!

But this was good news!

Happy to help -

Maybe you can borrow another keyboard to see if it is a problem with the keys on your present one.

Jorgen

Christoph,

Geir is absolutely correct, the thread he references has a couple of solutions worth trying, and my post in there tells you why this is happening.

If the error persists in spite of these suggestions, then please post your system specifications.

Jorgen

Rory, The keys function fine in my v. 5.4, and the client there has not been changed since the latest v. 5.4 client came out and I installed it. I only have one add-on aircraft installed, Dino Cattaneo's freeware T-45 Goshawk. I am at a loss to say what could have happened on your system, but (accor...
