Hi Peternlewis.
Thanks for your help.
The first command’s result is:
bottom = 793;
left = 1330;
right = 1597;
top = 439;
I have 2 screens : the internal one of the MBP and an other via the HDMI port, in copy mode.
value of the token %Screen%Main% is 0,0,1920,1080.
”Place Conflict Palette Under Mouse” in the Palettes preference was already enabled.
After reading a response to my another problem ( Problem simulating a keystoke - #3 by kevinb ), I went to read ‘Troubleshooting [Keyboard Maestro Wiki] in the wiki.
KBM is effectively launched as Hidden by my system (via the application Startup Manager Pro), II tested to unhide it and bingo ! the conflict palette is now displayed …
The wiki says that “This appears resolved in Mavericks”.
And indeed, I had never had this problem.
It comes back with Tahoe… Thank you Apple !
I'm going to continue testing all this...
