Is there a way to lock a window's position?

I have one (the album art plugin for winamp) that just won't stay in the same position. And curiously, the activate command I use (in TCC shell) to move it to a specific location.... Is inconsistent as well.

I'm wondering if the numerical (but not positional) order of my monitors is changing sometimes, but honestly, the relative difference in where i have to place it (1430,-800 vs 1926,-660 vs 1030-800) wouldn't suggest that.

I could be done with this whole debacle if I could just lock the position of that window at a fixed point so that nothing can ever move it (without always-on-top being set).

Is there something like this in DisplayFusion that I am just missing?
