i have installed eclipse ide java developers (version: 3.6.1) android sdk platform 2.1update1 - on windows 7.

i can add, edit , run code projects, however, in workbench area graphical layout view of layout xml files shows "missing theme" message in bottom right navigation area.the left palette navigator area ok , remaining area blank.

the error message reads: "selecting page '0' in androidxmleditor failed"
