Fsbuild-2 Flight Planner

Hi Ernie, and hi everybody.

I just installed ISG1 V1.8+1.87 and I'm having a crash when I finish a flight and the sim tries to return to the main page.
The FSX interface disappears and I have to end the task using the task manager.
I have a very simple panel on the King Air 350 with EF50, EHSI, GNSXLS and TCAS (displaying on EHSI).
Everything seems to run smoothly, but everytime I finish a flight the sim crashes when trying to go to the main menu page.
This is a very fresh FSX installation with no any other addons.
I also tried with v1.8 only and the problem persists.
However, if I remove the TCAS, it doesn't happen, so it seems to me that the sim crashes due to this gauge.
Any ideas of what this might be?

(I'm on Win 10 64bit, althought FSX installs on the 32bit folder)
