I have 2 editor windows ("Source Editor" and ""Source Editor (2)"
and have loaded "Unit1.pas" in both of these windows.
After I have now (inadvertently) closed "Unit1.pas" in "Source Editor"
I cannot load it again with "File Open".
It just happens nothing.
A known bug?

True.
But Unicode should have cared.

In one of my Windows programs I use a splitter to separate two VirtualTreeView

The relation of the heights of these two VirtualTreeView components should be

In my program the "Procedure List" function (Ctrl+G) does not

Is there a restriction to show only functions of level depth 1?
If yes, why?
I did not found any options influencing this.
