SysQueryForm "Reset" Button

[paucer]

How to menage "Reset" button in SysQueryForm?

The problem: system loads old sorting and ranging values from SysLastValue. But must I print a report having only one record with the new data.
Of course the user can press "Reset" button and everything goes ok. But Imagine if the user forgets to press "Reset"... (that is what usually happens)
The primary quesion - "How override "Reset" button click?"
As I see there is possibility to drop certain SysLastValue record. so
the secondary question is - "If there is no need to bother with the "Reset" button control, may be there is some class that manages SysLastValue? How this could be done with the class and SysLast Value"
Thanx in advance
