I have encountered this problem that my Command Section overlay (F3) is not opening any longer.
I am running V1.7 but had this problem also in earlier versions.
First I thought it had something to do with connecting my commandwing and a certain showfile I was running, as it only seemed to be a problem with that file.
Now I have created a new file and all worked fine till I turned on my PC today (no commandwing attached with this file yet).
command line message is:
illegal destination list:Menu "commandcontrol"
Any help is muchly appreciated.
