Those concerned,

If anyone would like I can provide a more detailed example of how all
this works, and more properly per the use of Queues, as they are
technically not needed in this demonstration ( I could have use the
wparam and lparam )

This is actually rather simple.

Simple create a shared variable containing the a scalar handle to the
window, and proceed to "Win32::GUI::SendMessage($ts_winHandle, WM_USER
+2)" etc., thus allowing for no need to actually poll the Queue for
status, as the message stack for the window will *tell* when there is an
item in the Queue...

Sorry I didn't include that in the example, as it was dated from before
the weekend and I haven't been to this email account since then even
though I have been working on the ideas in my spare time at home.

A few months back I hinted at some code that Rob had built that would
make 
threading coding much easier for Win32-GUI apps. In light of your recent

examples, I've dropped him an offlist mail suggesting that his code be 
available to more people. Although not complete, it is a great platform
to 
build from.

One of the problems that Rob's code solves is that one end of a thread 
message queue can be attached to a window meaning there are no sleeps or

polling to check for new messages. Basically, it means that a working
thread 
can fire events in the thread controlling the window, resulting in a
very 
efficient and simple event driven threading model.

Cheers,

jez.
