Hi Crum,Linda I installed following all the instructions, (I work from 2 days, sigh!), PMDG 737NGX installed, and updated form. Beginning to be proceeding well, start the simulator, the display appears with the real measures mcp (SPD 100, ALT 10000 .. etc. ..) but when you start the diplay changes (SPD 000, ALT 0200) and when increase in the value of the altimeter for example, it only changes within the simulator, the question is: is this normal?Then when I try to push the various buttons on the combo, they work well, but only after 3-4 minutes, it stops working. I'm trying again for 2 days, but nothing to do, works only for those few minutes, then stops, and when I get out of the combo FSX remains fixed and I need a reset, but raising the simulator does not work anymore, and are forced to leave with the computer (general reset).I'm crazy but I can not solve the problem. I'd appreciate if you give me a hand.Thank you in advance

The NGX module doesn't currently support the display sync. We all waiting for SDK to be released. As for hung ups after 3-4 minutes of working.. this is strange. Tests for you to execute:- check if LINDA and your MCP unit will normally work with default Cessna- if it hungs up too, then check if it MCP will work normaly with SerialFP2 software + Cessna again. In fact there are no reasons for stopping to work after period of time inside LINDA code. If it works - it works.

Ok, Crum, i try ur method, I'll know after the tests, thanks for now
