loading the same file in succession does not work

[EricPraetzel]

Two issues:

1. Attempting to load a file while the simulator is running is exceptionally slow. Clicking on Load should halt simulation.

2. If you have loaded a file from your computer and run it;
   then edited the file and recompiled it;
   and you try to load the file in emulsiV, it does NOT load the file.

The program counter stays where it last was and no load happens.
The only way to load the changed hex file is to load something else and then load your hex file again.

Attempting to load a file while the simulator is running is exceptionally slow. Clicking on Load should halt simulation.

Actually, the load button is supposed to be disabled while the program runs.
In my tests, the simulator prevents loading a new file but the button itself is not grayed out.
This should be fixed now.

If you have loaded a file from your computer and run it

I think I know why it behaves like, but unfortunately, I could not reproduce the issue: in all my attempts, I could reload the same file multiple times in Firefox and Chromium.
I have just uploaded a fixed version. Please tell me if it works better for you
