The value property of a combobox that is in a grid changes unexpectedly and inappropriately when I tab to the page in which the grid lives and set the page.fontbold = .T. I presume that when the fontbold gets changed some sort of refreshing takes place, but the controlsource of the combobox has a different value, and I think the combo.value should remain equal to the controlsource value.

The combobox has the following properties:
Control source: relhortur.idTur
Rowsourcetype: 5 - Array
Rowsource: Thisform.aTurnos
ColumnCount: 2
ColumnWidths: 100,0
BoundColumn: 2
BoundTo: .T.
Style: 2

By the way, the controlsource of combobox is in a different table than the grid's controlsource but the tables are related.

What's happening? Thank you for the help.
