I'd appreciate another BT user trying to reproduce this very odd behaviour please.
If I have BT as the active window, but in quiet mode (i.e. not playing the show), CPU usage is typically very low. My whole PC is using about 2-3%. I've shown that normal situation in this screenshot:
dl.dropboxusercontent.com...
But if I now switch to any another application, CPU usage of BT jumps up to 22-25% - but ONLY if the application entirely covers the BT main window!
I've tested this over the last half hour with consistent results.
I'll repeat later after a reboot and BT restart with another simple show.

No one able to try that simple test please?
If any other app fully covers BT, total PC CPU usage here jumps up from close to zero to around 25%, and all of it is used by BT.

Nope, not here tried with several programs like photoshop, videoplayer, blender e.d. but no effect according to taskmanager.
It does remind me of Groucho Marx:
I said: "Doctor, it hurts when I do that.:" (patient moves his arm)
Doctor: "Then don't do that."

Thanks for testing, komies.
It may be irrelevant, but I expect you're using a more recent OS than mine? My ageing PC is a Quad Core 2.66 GHz, 4 GB running XP Pro (SP3). It has a 512 MB nVIDIA GeoForce 8800GT. I gather BT makes special use of the graphics card RAM, so wonder if there's a clue there?
I'd avoid it if I could! ;-) But many of my major apps take up much or all of the screen, so the sudden CPU surge is largely unavoidable. BT immediately gets hidden when I switch away.
Of course, the work-around is simply to save the current show and close BT, re-opening it later. But I'm very curious to know the cause.
