I'm running the most recent stable build of indie LS under windows XP and I'm experiencing an odd problem. For a select few programs, sub windows will not close not matter how I attempt to kill them, namely Trillian, Gaim, and Klipfolio. However, when I terminate Litestep, the windows close normally. Can this be a bug in Litestep, or is it just poor code in the programs?

I have used Trillian and Gaim and have had no such problem with closing applications.
