I found that attempting to set any of the Font properties in
the InteractiveChange causes the text to be displayed backwards.

This bug appears in VFP7, 8, and 9.

All of these produce the bahavior:

This.FontSize = 12
This.FontBold = .T.
	
This.FontBold = NOT EMPTY(This.Value)
			
This.FontBold = (This.vLastValue <> This.Value)
This.FontName = IIF(This.Value # This.vLastValue "Arial", "courier new ")

>I do not know if it is a bug or not, but I think is because you access the .value property and each time the .value property is accessed, it seems that resets the .selstart property. But, I am not sure, I just saw your code and tried it, and while typing in the textbox to check it, I saw that behaviour and thought of a workaround, I leave all bug reports to Fabio <g>
