I have a listbox control in form.
When some of its rows is right-clicked, I want that this
row will become active row, higlight and value move to it as
in windows file folders.

Currently, it is required to select the row by left-clicking
and only after that right-click works.

However, if I right click many times different rows, sometimes
some clicks work as expected, i.e. will activate new row.
But in most clases right clicking does not change active row.

How to make current row active when it is right clicked ?
