thanks for your interest. i've had the CP theme for some time now and have only recently decided to use it. we upgraded to v3.0.5.2 from the old 2.9 version and purchased the SB upgrade last week, and then upgraded to v3.0.5.3 today. i was only concerned that not seeing a "big yellow" may be critical to proper functioning of the theme.
Well if you have already gone to 3.0.5.2 then the recent update won't be such a shock to the system then You will have already completed the migration during the last upgrade, so you shouldn't get the "big yellow" again
