It is not a bug.

The selection of one text field is lost when something else gets selected.

You can middle-mouse paste text from the field that has the selection into
some other control (FXText or FXTextField).

On X11, selection is system-wide, i.e. you can paste from FXTextField in
a FOX application to something that acceptes text, possibly in another

When focus is transferred to a FXTextField, text in the field, if there is
any, is selected.  The selection of the original FXTextField is lost only
as a side effect of the fact that there is only one selection in the system
[on Windows, we can only manage the primary selection within the application,
but on X11 its system-wide].

Hope this explains,
