Jeff, thanks for the quick response, here are my answers to your questions:

1. No, I am using the default BP themes for home and members.

2. No.

3. Yes there are plugins installed => bpPictures, Sitewide Newsletter System and Community Blogs. I did disable them without any change in behavior.

4. Good suggestion, I did now go through the error log after repeating the steps and found no errors reported.
