Hi Cathy,

>How can I keep the last active cell highlighted when the user leaves the grid?

In the AfterRowColChange, try this:

Thisform.nRecord = recno(This.RecordSource)
This.SetAll('DynamicBackColor', '"rgb(255,255,255)"', 'Columns')
This.Columns[nColIndex].DynamicBackColor = "iif(thisform.nRecord = recno(This.RecordSource), rgb(0,0,255), rgb(255,255,255))"

You will probably need to tweak this a little.
