how to rid myself of warning -- in 1.0.6

[brent verner <damonbrent earthlink net>]

i built an app i'm doing some work on with 1.0.6 to see
if it would build... it did, but i get this warning message.
does anyone have any idea about where i should look to 
get rid of the warning?

** WARNING **: could not determine signal number for event: 28

thanks!
