Some further specifics I noted so far.

If I try to open my main region, I get the error message. If I try the other ones, nothing seems to happen, however, keyclone trays will spawn like mad in the start icon bar. (bottom right thingy) if I spam trying to open one of those instances. If I mouseover the icons, they poof again. Appearing to have been terminated right after start up but exited incorrectly perhaps.

Also, if I tried to open some of those and attempt to exit keyclone. It won't exit at all and I have to bring up task manager and end the proces for it to exit. Otherwise, it simply won't exit.

*shrug*

So, seems to be related with maximizer, somehow, and it started after a system crash. :P
