Unhandled exception when compiling library for FSX

Hello Don,

I'm a new user of AFLT and needed to create an array of approach strobes for my project. I managed to write the def file and compile it successfully for P3D. Simobject mdls and everything created and the strobes show and flash fine at their correct exact location in sim in P3D v4.

However, when I try to create an FSX version using bgl lights I get an unhandled exception message when compiling the library. If I choose to ignore and continue, the compiling never finishes. I tried both the current and the development versions with the same results.

Any help would be appreciated.
