Hello,
My previous question posted in the UT (Multiselection in a listbox) is superceded by what I've just discovered.
I created a multiselect Listbox on a blank form and it worked perfectly. I used the exact code in a MDI application and it would not Multiselect. Therefore, I've concluded that there is something unique about the MDI form that I'm not aware of that prevents me from using the Multiselect options.
Does anybody have any ideas here?

TIA
