WPG3.0.X dosen't work with WP2.7 (Editorproblems)

Hi,

i tested around for 2 hours after my upgrade to version 2.7 of wordpress. Now i got an error and a specified WGP that will make the trouble.

If i like to blog arround the editor want load the tinymce editor complete and if you switch to "visuell" the buttons are complette gone and there are white signs on a white background.
A little Picture:

You see that the complete row with ethe standard-tinymce buttons are gone. That the mainproblem.

That my blog. But i installed a complete new installation in a different subfolder and the only plugin are ? -> WPG3.0.6 and after the activation of this the error came back. Without WPG you can wrote and blog with the complete Editor into Wordpress.
