When I do [Execute] [String], if I just do it once I disable the shift button and change what the focus, color, etc...buttons do. I can't get it back doing anything except for again pressing [Execute][String] which does seem to fix it (as does existing or restarting). I have experienced this on the both consoles I have used strings with. Both are older consoles with the multi-pin DVI connectors. I am running 2.3.3.9.0.10. It doesn't seem to matter if I actually put something in or just clear the command line after doing [Execute][String], the problem still corrects/creates itself.
