I'm porting my addon from FSX to P3D, and notice that P3D crashes on exit when running my addon, which is comprised of both an EXE and a DLL. After some investigation I have determined that the DLLStop function is not being called at program shutdown, and so my app is not able to close the handle to SimConnect. The problem is not specific to my application ... I am able to reproduce the problem using the sample DLL client found here : http://archive.msdn.microsoft.com/ESPdllSimConnect. The problem manifests no matter what version of SimConnect I build against. Looks like a P3D bug to me.

Hi Russ,

Yep, it is back. The dev team have identified it and it will be in our next patch. It is a P3D issue and not your addon. It only affects closing of P3D when there is an addon. Looks horrible, but it will be fixed.

I have also found this necessary, for some of my SimConnect exes.

Even when DLLstop is able to be called correctly, there is always the chance that the Sim may Crash, and your program then would not get closed. If this is a potential issue, you might want to monitor the Sim application process in your EXE, and if it is not running, take whatever action is appropriate.

Any idea on when this patch/fix is going to be released? I'm going live with my addon probably today or tomorrow. (www.fs-force.com)

Actually, its a completely different issue :-> In this case, its related to addons that create one or more menu items, SimConnect and the menu system were having a little fight on shutdown.

I'm in the midst of doing the initial port of the VRS TacPack to Prepar3D and am seeing exactly this issue. (Crash in menu.dll on shutdown if I create menu items via SimConnect) I'm using Prepar3D 1.2.3253.0 (SimConnect 1.2.0.0). Is this version known to be affected by this bug? Any ETA on a fix?

Alright, thanks.
