I don't think so but I'll have to look to make sure.
Check that the send_footer function has been modified accordingly. Missing variables in the "global" call in this function may be the problem. These variables will be the deciding factor if the right sidebar is being displayed.
The left sidebar is displayed during the "send_header" function and closed in the "send_footer".
The right sidebar is opened during the "send_header" function but displayed in the "send_footer" function and closed.
Hope that helps. I'll try and take a look as soon as I can. Maybe someone else has already got this modification rolling with 6.2.2 and can chime in with any changes they made.
