Hi guys,
recently some users reported that sometimes Action! is blocking their Steam Overlay. By analyzing lots of reports our support team came up with a solution. Please check if it works for you.
In one of previous Action! versions we've added a simple feature that allows you to exclude specific applications so Action! will simply ignore them.
One of Steam processes when you are running your Steam game is "GameOverlayUI.exe". Add this process to your exclude list. If you don't know how to add files to exclude list go to our tutorial here: http://mirillis.com/en/products/tutoria ... t.html#top
Let us know if that works. Your feedback is appreciated.
Edit:
One of our users confirmed that "gameoverlayui.exe" works for Win 8 x64.
