xonclock using too much CPU

[Lee]

There seems to be a CPU leak in xonclock where once in a while, after running for a few hours, xonclock disappears from the screen and starts  using up most of the CPU time.  I've seen this at least a couple of times lately.

Is anyone aware of known bugs in xonclock that might cause this  - and/or known fixes or workarounds?

Please see the attached screen shots of my conky display.

I'm using micro core 4.0 w/Clibs, Xprogs, Xorg-7.5, wbar  and jwm.
