Testing turns out to be unnecessary.  The problem, based on comparison with
function under WinXP, is tied to app action and appears under WinXP, too. 
There is, however, a notable difference between main window and system tray
action under Windows and Wine, and it has a direct impact on what is seen under
Wine.  

Under Windows, if the option to maintain a system tray icon is enabled,
minimizing the main window causes it to disappear from the task bar altogether.
 It can be restored only if a display or graphing format other than the checked
format is chosen.  That is, if realtime, in the format list, is checked,
choosing it again will not restore the minimized (and no longer visible)
window.  Choosing, for example, graph format would restore the window, with the
graph format now displayed. 

Under Wine, or at least under wine under Gnome/metacity, minimizing the main
window does not cause it to vanish from the task bar but to act like any other
minimized window.  Restoring it, then, would be effectively attempting to pick
the same format already in effect, which under Windows, has no effect, but
which, under Wine, causes a window frame and decorations to be drawn, with no
content save whatever was in the window boundary as it was drawn (i.e.,
nonsense content).  

It is likely, therefore, that no bug, per se, exists unless it is possible to
duplicate the action, described above, seen under Windows; that is not now
happening.  At worst, this is a minor problem and a reminder to the user not to
select a display option already selected.  It can be reasonably argued the
app's author should handle this condition better even under Windows but that
change isn't likely, given the present lack of contact with the author.
