fwiw, I was having the macro key issue on K95 since last update. Simply updating iCue did not resolve the keys from spazzing out.
But I noticed that after updating to this version, that the offending macros now show up as entries in actions library accordion (not the actions accordion), for the K95. I removed them and my ESC key macro issue appears to be resolved.
I have a K95, no macros or special assignments on the esc/F-keys, but after upgrading iCue to 3.22.74, when I hit ESC, the "slide right virtual windows" event is triggered. In addition, the F1 key triggers the "view all virtual windows" event.
