Cant quite get it

I have a main movie, a shell if you into which i load all the external content via a global history command and loadClip() the problem well not problem but minor issue im having is that when i load the content into the shell i am unable to use the keys, just the arrows, to go to the next and previous frames, needless to say it works fine when im testing to content on its own but from the shell no go. Ive tried a few things to no avail, so was just hoping and wondering if someone could help ??
