[FIXED] DCS freeze using autopilot (2.5.6.50979)

Tried the new patch, the lighting problem seem to be fixed. The blue tint is less visible and the autopilot and afterburner lights are visible again.

But I've encountered a new problem. In order to try the test the lighting (autopilot lights visibility) I switched the autopilot on and off while on the ground a couple of times. After 1-3 switches DCS freezes. I've been able to recreate it several times now.

While DCS freezes it doesn't go on a CPU och memory rampage like earlier bugs. It just freezes and I have to kill the task.

As we say in Sweden: it's a choice between the plague or cholera, in this case crash/freeze or bad lighting. :D

Any thoughts on this? I really like the autopilot in the Viggen, and would to continue using it. :thumbup:

Hmm, I seem to have narrowed it down.

I can enable and disable the autopilot repeatedly without any freeze - when in the air.

As soon as I'm on the ground again and enable the autopilot, DCS freezes. Sometimes it takes a couple of presses, but still just a few. So it's pretty simple to recreate.

Yes, I understand that there's no use for the autopilot while on the ground, but remember I accidentally discovered this when testing the autopilot button lighting.

I'll just have to be careful not pressing the wrong button while on the ground.

Make the Viggen freeze 100%:

Start from runway, and before finally hitting the green FLY button to start flying, enable autopilot HÖJD (e.g. by using a switch on the A-10 Warthog throttle).

Viggen freezes instantly, saying this:
