Prevent Excel From Capturing Keyboard While Editing Design Tables

Hello, 

I've programmed a macro that uses design tables to create assemblies. When the macro is running, whenever it opens excel to edit the design table, my keyboard is captured and I end up messing up the design table if I was typing an email simultaneously. Is there a way to prevent this? Meaning, have the macro work in the background while it's editing the design tables?

Thanks!
