Hi,
Finally I had some time to test this. I created a timer and inside it I
call:
printf("CURSORPOS=%s\n", IupGetGlobal("CURSORPOS"));
It kept printing valid values even when I move the mouse to other
monitors. Also I activated other applications in the secondary monitor and
it kept working. I move the application itself for the second monitor and
it kept working. It is still working while I type this in a different
monitor...
There is something else going on. I'm on Windows 10.
This is a sample from the log:
CURSORPOS=8080x1181
CURSORPOS=8080x1181
CURSORPOS=7902x1062
CURSORPOS=7902x1062
CURSORPOS=7773x1061
CURSORPOS=6325x914
CURSORPOS=1913x715
CURSORPOS=1880x725
CURSORPOS=877x727
CURSORPOS=393x387
CURSORPOS=1x230
CURSORPOS=46x40
CURSORPOS=18x24
CURSORPOS=19x25
CURSORPOS=19x25
CURSORPOS=19x25
CURSORPOS=1167x703
CURSORPOS=1604x943
CURSORPOS=2388x1379
CURSORPOS=3509x1964
CURSORPOS=3752x2046
CURSORPOS=6419x1595
CURSORPOS=7381x1410
CURSORPOS=8955x1726
CURSORPOS=9211x1488
CURSORPOS=9202x1602
CURSORPOS=9206x1605
CURSORPOS=8272x1043
Best,
Scuri
