Modals Blown Away

[Ray]

Is there something wrong in 7.0.2 with this?

/modal stack [stackName]/

It's a substack, but even if I use

/modal stack [subStackName] or stack [mainStackName]/

Livecode simply blows right by it.  I get nothing in the result and 
nothing in a try-catch.

This is super finicky, working sometimes, not working others, and then 
suddenly working when I did nothing different.

Anybody know anything about this?
