Hi Kasper, I was wondering if you have any additional thoughts on the warning message below that you said "does not look nice." Any idea where it came from, how to fix it, or whether it matters? I'd really like to use bumphunter, if possible. Thanks again! Allegra _________________________________ Allegra A.
