Hello
I think I found a bug in ListBox, namely the receipt of messages from Windows by this component.
I did an example showing a problem.
There are two page Memo and ListBox
each of them contains the "Start" button after pressing which after hovering the mouse over e.g. memo and clicking the button, displays the message (memo, button) in the case of the first tab in the case of the second one (listbox, button) and if everything works correctly for the memo tab, there is a problem on the listbox tab because what we would not click is the message that will be displayed is "listbox"
The program demonstrating the problem is attached
I would try to correct this mistake, but I don't know where to start. Maybe I can tell you something.
