Remember that bug with the slider in the mutations window?
The one that always goes back to the centre?
I found the reason.
It seems that every time you run or load a sim, the value of "SimOpts.MutCurrMult" (the variable attached to the slider) is set to 1 by the program.
Now why the heck would somebody DO that ? :blink:
It looks like it might have always been that way since all the way back to V2.11.
I just commented out the offending lines and now it works just fine.
I hate bugs like this. :angry:
