[Fractint] Bug in float-only 20.02.5

I have found a rather serious bug in the evolver feature of the float-only version 20.02.5 of Fractint. When the evolver feature is on the screen, striking < f6 > should bring up a screen that lets the user choose which parameters to change. But in the float-only version 20.02.5, striking < f6 > merely returns the user to the original image. This feature was working correctly in float-only version 20.02.4. Jim M.
