I have a ListBox as part of a form with other controls. Pressing the Tab key does not seem to focus into the ListBox with the other inputs on the screen, so this makes keyboard navigation difficult.
Here is an example:
Put the cursor in the textbox 1, then type Tab, which should go to textbox 2. Then type Tab again, and it does not move to Listbox1.
If you tab from Listbox1, it will move to Listbox2. Listbox2 will tab to textbox1 oddly, but will never get the focus again.
