This has hit me a couple times. I will go in and enter a value take for instance flow multiplier. enter the value 0.05 and press enter enter dialog closes. You would think it accepted the value, but 0.1 is the smallest since 0.05 is too small it close the dialog and resets back to 1.0 with no warning.
If a value entered is outside a limit or bad data have a warning dialog popup saying so.
not just close and reset back to the previous value. If it closes you would think the value you entered was acceptable.
I am now getting in the habit of tabbing off the value I enter and verifying again it did not reset because it was outside of some unknown limit.
