Contextual alternates in Corel Draw

Is anyone here working with text in Corel Draw? I made a font that has a few alternate letters made as CALT. My client works only in Corel Draw and says these alt letters does not appear when she types or highlights them. I’m not familiar at all with CD. It works for me in both Illustrator and InDesign, the letters pops in by default. Anyone knows what I can suggest to my client?

Maybe download a demo version of CD? Use a virtual machine (and snapshots) to not mess with your system. Then you can try yourself.

The Corel website says that it should support contextual alternates:

I already had the demo version and it expired today unfortunately. Didn’t get time to check this matter. Yes it says it does that’s why I was wondering…
