I have recently deployed an app where several users will only have the 2010 RunTime version of Access installed. One of those users is seeing things that I don't see. When a selection is made in a combo box she is getting the dialog box that one would see from a parameter query. For example, she gets a box asking for this value: [Forms]![frmLocation]![frmLocationView].[Form]![cmbRegion]. This could be coming from a query or the row source of another combo box. Doubt that matters though.
When I open the file using RunTime everything works just fine. The same is true for other users as well. Any ideas what could be happening?
