Hi Reza,
Because you call method SetFocus() of any object in form GetInfo.scx on running it and you call this form from any this event (When, Valid, RangeHigh,RangeLow event). Check if any event from preview list is in Call stack.
This is not bug, it's feature. Check pass-word for method Setfocus in Help .
