I thought I was going nuts. I bought the k95 last week and downloaded the latest icue. I noticed the problem when I was loading and saving in Duke Nukem 3d.
I have a G key linked to launch steam and it would launch steam every time I saved.
I went to a keyboard tester website and noticed function keys using the macros I made.
A G key I set as ALT+F4 would always use CTRL too. Went around looking for the problem that was causing this. Glad I am not alone with this issue.
Downloaded version 3.21.88. Problem is solved now.
