Unfortunately this is part of a framework with a poor debugger I spent quite time with no success yet.
Other then lockscreen what may be causing this dynamicbackcolor expression behave strange :

this.setall("DynamicBackColor",;
 "iif(recno(this.recordsource)=this.nCurRec,YELLOW,WHITE)",;
 "Column")

-Grid is on a "child" pageframe, parent is a view, grid is a table.
-When it first shows up all rows are YELLOW.
-When it gets focus everything is normal.
-If I go to just another form and come back again all rows are painted to YELLOW ???
-I already tried overriding "activate" for form and pages.
-The same framework, same class grid behave normally where parent is not a view ???
-In all cases parent's buffering 3 and child grid recsource 5.
TIA
