JAYELBEE  I've been using Macs since 1985 (or maybe it was 1984...) and was sorely missing the Mac's traditional rounded screen corners in Leopard. This program does exactly what it claims -- rounds the menu bar corners in OS X 10.5 -- while using very few system resources. It appears to consume virtually zero CPU cycles and, after running for a couple days, is currently using less than 1MB of private memory (7MB of real memory) on my PowerBook G4.

Thank you for this excellent little utility!
