I used a similar utility (Peek-a-Boo 1.6) to monitor the CPU usage for
VueScan 7.5b1 running under Mac OS 9.2.2.  I started VueScan and put it
into background without doing anything.  The monitor showed that VueScan
is using about 50-60% of CPU time while idling in background.  Not very
nice (in the unix sense and in common parlance).

Perhaps wxWindows has settings for adjusting the level of CPU activity
when in background.  I hope Ed can look into this.
