wanders when used BTT

Hi there.

I have BTT on my Macbook air with an M2 chip.

I have the problem, when I am using the BBT float on top, the window I wanders, and sometimes it stop working. Is there something I can do to changes it, so it works all the time. It is a bit irritating to use it and then the site I have under, the site I have float on top, is somehow above the top floating site.

I anyone else have the same problem?
