php4ever, while your plug in is not supported anymore it is the only thing available right now to integrate Open Realty and WordPress. It has a lot of bugs, but right now it’s all we got :(, so until something else comes along a lot of people are going to continue using it.
The only way to fix this is using a plug in called iFrame Admin, don’t know why they wouldn’t address this issue, but this other plugin allows you to view the admin pages in a large iframe verses the wp-realty postage stamp.
