The only 100% effective way, and it's expensive in terms of overhead, is to insert a UDF() in the WHERE (and if in use, the HAVING clause as well) that calles DOEVENTS(). VFP is not happy being interrupted in the midst of executing a single line of code, with the result that it oftens seems to be not responding in Task manager, and it ignores standard Windows messages in this context as well.
