I had similar problems when skipping between parent records after manipulating child records in a Grid. After DAYS AND DAYS I solved the problems by selecting the PARENT table and the refreshing the whole page:

blah blah blah
select orderdetails && child table
replace last_mod with date() && make change in child table
blah blah blah

SELECT ORDERS && Parent table
THISFORM.REFRESH && refresh everything


I hope this helps.
