Same issue as 41159 in NB3.6.

NB4.0 IDE 2004 08 15 1800
JDK 1.5.0 beta2

NB 4.0 is not compliant to XP multiple monitor 
setup.
(On the other hand, the argument goes, do we 
have to comply to Mr Gates & Co?)
Nevertheless (since I'm more interested in 
having things work regardless) ...

I have set my XP laptop screen as primary 
display and another monitor as extended display.

I moved netbeans window to the extended display. 
I right clicked on the editor, the pop-up menu 
appeared at the extreme right of the primary 
display. I selected a range of text, right 
clicked on it hoping to copy it - but the menu 
appeared far away into the primary display, 
while my mouse cursor was at the extended 
display.

This misbehaviour is not consistent ...
I right-clicked on the output window, the pop-up 
menu appeared correctly on the extended display 
at the spot of mouse cursor.

Now goes the kludgier misbehaviour - the top 
menu.

Menu       Where drop-down
Item       is displayed

File       Primary
Edit       Primary
View       Primary
Build      Primary
Run        Primary
Refactor   Extended (correctly)
Versioning Sometimes here, sometimes there.
Tools      Extended (correctly)
Window     Extended (correctly)

I wanted to list this feedback as a deficient 
feature. However, since the extended monitor is 
recogniseable but not consistently, I feel this 
is a defect.

Obviously, two sets of algorithms are at work 
here, but there should consistently be only one.
The first (erroneous) algorithm must have 
clipped its coordinates to the extremities of 
the primary display.
The second (acceptable) algrorithm does not 
constrain itself to the primary display.

I can't see how we could attribute this to 
unresolved bugs of JDK. If it is an issue with 
JDK, why is multi-monitor correctly recognised 
by some windows/menus?
