Fenix Pop-out Windows - Where did they go?

I have a dual 32" monitor setup with another small 5x7 LCD that I use to pop out the EFIS and the HSI in the Fenix A320.  For some reason now when I right-alt, get the "plus" sign and then left click, no windows pop out.  I don't have any other desktops set up or odd configurations that I know of.  The monitors are set to their native and recommended resolutions.  Anyone else have this strange behavior?  Any ideas?

Thanks.
