1. First, make sure you download the correct version. For some reason, in my Google search, version 1.5.0.1415b is at the top, not version 1.5.0.1416b. The 2nd listing is the correct link. I ended up upgrading to the wrong version without noticing.
2. Possible administrator-setting change after upgrading to 1.5.0.1415b
I have a lot of AutoHotkey scripts running on my computer. For example, caps lock key+s toggle-opens and closes Everything Search.
After rebooting, the Everything interface ran at high integrity while my normal applications and AutoHotkey scripts ran at medium integrity. This caused global AutoHotkey combinations to stop working while Everything was focused. It also caused my caps lock key to be stuck in the down position every time I pressed caps + s.
It took me hours to figure out that my scripts were screwing up because of the recent Everything upgrade. (ChatGPT finally figured it out.) I had to disable the administrator setting. That's fixed the problems I was having with my script.
Good luck!
