auto-reload on run NC files

When I run a NC file it is reloaded automatically. Every time. Even [resume on given line] is selected. (The [R] button isn't needed any more.) Can I prevent it from doing so?
(I use a python GUI to generate the NC code. I dont want fill in all parameters very time I start the run.)

LinuxCNC/AXIS Version 2.9.1

Yes, a python filter. But dosn't matter. The problem is with ordinnary nc-files as well.

1. Load a nc-file (plain gc-text).
2. Edit the file.
3. Run program - you'll run the modification.

Well, thank you allot. Both deal exacly with my problem. But I got dizzy and lost by reading. What is the conclusion? No easy fix?
When was this 'feature' introduced first, in other words: which older version should I use instead?
What next? Guess I should switch over to on of these toppics.
