This is a core difference. Our application is pretty much event driven.
Some events maintain a task list that is worked through when there is
nothing else to do. One of the BIG problems when we went to a GUI is
that we lost the direct connection to the keyboard as an event device.
It now goes in the X queue. This is because X needs to process these
things in some order to see where the key press needs to be sent. In
fact, any window system probably has this constraint. So, we opted for a
special USB key strip that can be used to generate timely user events.

I will do this.

I do like Tcl. I think it is a good scripting language. What it adds is
platform independence in the scripts and the GUI.
