>First off all, it's Microsoft's design. It is the default behavior of the combobox. A single click is enough. If you do a second click (which isn't the same as a double click) and if there is another object exactly below the cursor, then yes, of course, it will be activated.

Yes that's true, but doesn't negate the fact that your design allows for this behavior. Change the design so the next clickable item is not under the combobox. You owe it to your customers to help prevent I-D-10-T errors.

End of my posts to you on the subject. You circumvented the real issue with Jos and I will not be dragged into this.
