The RadComboBox with RadFormDecorator problem was indeed reported after you did, but it was in a support ticket (which have higher priority) and I first saw it and reproduced it from there. Also the support ticket included a sample project which reproduced the problem directly. I didn't mean to offend you.
The RadTabStrip problem was first reported on 4 November and your report is from 5 November.
