Broken glulx files?

Hey, right now I’m developing my first game and I am using Inform (1.2 6.31/6H98).
I have to use this Version because of the GerX Extension.

I’m using Z-Code and it works in Inform, in any Client and in any Browser.

But now I’m getting to the point at which I want to use extensions which are Glulx only :confused:

And if I compile the game as glulx only a white screen appears. In the Client and in Inform as well. But in the Browser it works!

Any idea?

Thanks a lot

All versions of the Inform IDE are broken on MacOS 10.12 (“Sierra”). You can get an (unofficial) working build of 6M62 at , but I don’t have any earlier versions.
