100% CPU Usage when starting Win32 process through cron

I upgraded my cygwin installation to the latest one but the problem still exists. I still
see the process occupying 99% CPU time. One thing that might be worth mentioning is that the
WIn32 process is accessing the audio/video card(s) device drivers. The process works fine
functionally except for the CPU usage. Here's the latest cygcheck.out file after update
(this is on the WinXP single CPU box also exhibiting the same behavior). Any pointers
please?
Thanks in advance,
