[amibroker] parameters display and formula

[L V Gandhi]

Initially I had parameter line as follows
ATRFactor = Param("ATRFactor", 1.5, 1, 3, 0.25 );
I changed it as follows using edit formula option
ATRFactor = Param("ATRFactor", 1.5, 1, 3, 0.1 );
But parameter windows changes in steps of .25 only not in steps of .1. What
should be done more to get latest edit to work. This happens even after
reopening ami and also restarting windows.
