I'm sorry :-) try this:

1) Set Map Window YourMapperID Redraw Off
2) Set Map Window YourMapperID Remove Map Layer SomeSelection
3) select * from SomeMap where <your_criteria> into SomeSelection noselect
'Warning! this Mapper with id YourMapperID must have more than one layer 
(SomeSelection).
'If mapper have only SomeSelection then after executing line 3 it
'will be closed
4) Set Map Window YourMapperID Add Map Layer SomeSelection
5) Set Map Window YourMapperID Redraw On
