Hi Claudine,
That is a very common symptom when performing long running
time-consuming routines.
There are a few techniques to improve such performance.
01. Use of PROCESSMESSAGE command in WHILE ... ENDWHILE loop.
While process a time-consuming routine and displaying the PAUSE 3
message with GAUGE, you also implement the the use of PROCESSMESSAGE
command that processes messages that are currently in the windows
message queue.
The PROCESSMESSAGE can help in the GUI part to avoid the "Not
responding" behavior in Windows operating systems. A common use of
PROCESSMESSAGE is in long WHILE loops.
PROCESSMESSAGE may be called in each loop iteration to give the GUI
time to process the pending Windows messages. For a loop that only
does data processing, PROCESSMESSAGE can also be used. It is advised
to disable GUI update settings like UINOTIF before entering the loop
with PROCESSMESSAGE, to counter some side-effects of PROCESSMESSAGE.
It is also important to not overuse PROCESSMESSAGE. Use the command
only in places where it is necessary for the GUI to "breath" during a
long running task.
02. Use of NO_FOCUS option in PAUSE 3 and PAUSE 4 Commands
NO_FOCUS option specifies the pause will not be focused when
displayed, which can be used to possibly prevent an interruption in
the focus transition in an active form.
For further details and sample examples, please refer to HELP
PROCESSMESSAGE and HELP PAUSE options.
Please feel free to reach out to me if you need any examples to
illustrate the use of such techniques.
Hope it helps!
Very Best R:egards,

I've meant to ask about this for quite some time. When there is a
somewhat lengthy process, "Not Responding" will occasionally pop up
at the top of the screen. Users often click on the x to exit the
screen but the process is really still working and just waiting will
let it complete.
What causes this and can it be avoided?
TIA,
Claudine
