Ah, that did the trick. Thank you!

First of all, thanks for the cool plugin!

I'm running into what I would think is a fairly common problem though: RoundCorner seems to "destroy" any concave insets I create. Instead of trying to explain in words I've created a 2 minute video which demonstrates an easy way for me to reproduce the problem.

Any ideas or help would be appreciated!

Thanks,
Eddy
