Since a few months ago, I can no longer change the mod loading order by click and dragging: When I attempt to do so, Mod the Spire will start using up a full cpu core, and will hard-lock the desktop.

By Hard-lock I mean to say that it grabs exclusive control of the mouse and display: rendering you unable to even kill the process, except by say remote-ing in to your own machine over SSH, making yourself superuser, listing a process list via the kernel, and kill -9 force-quitting the process. It's also possible to switch TTYs and do so if you have this enabled in X.

Problem likely linux-only and/or system dependent.

I'm aware that letting apps do this is kind of an X windowing system security issue but still, I think this is rather critical, even if it's linux-only.
