This is a followup to my previous post about an unusual behavior in comboboxes in which use of the .dropdown method in the OnEnter event would cause the dropdown to close if the user hit the combobox’s dropdown-arrow symbol instead of tabbing into the control.
As it turns out, this only happens if the combobox is sitting directly on a tab page! (it doesn’t happen if the combo is in a subform sitting on the tab page.) The attached db has a single form that demonstrates this. Notice that it doesn’t matter where the focus is prior to click on the combobox; it can be on the tab or outside it. The combobox on the tab always demonstrates this odd behavior if the dropdown arrow is clicked.
