Hi. I am new to AutoHotKey and I am absolutely loving it, but
sometimes it seems to go into "Windows Start key" lock or Control
lock, so that when I press "h", for example, let's say while typing in
an email window, my Start-H shortcut is activate, which launches
another application...

it's very annoying and makes AutoHotKey unuseable for me.

this usually tends to happen after I lock my computer and then come
back to it.

I noticed that pressing Alt and Windows key several times, (and then
the other, several times) usually makes this behavior stop...

what's could be causing it and how can I fix it, please?

Sincerely,
Aleksey
