Illegible Font in Dialogs
This happens in many places throughout your extensions. The attached image is representative of the problem. It is taken from the Site Import dialog. The image attachment was not resized by the forum attachment manager, it shows how the dialog looks on my PC (Win XP SP2, Dreamweaver CS3 build 3481).
Not all text in your extensions are illegible like this, but where the problem exists, the dialogs are very difficult to work with.
