We have 18 core themes + base and canvas. From these 20 themes

• 3 blog-style themes are fixed (nonzero, overlay, sky_high) and work as they should
• 5 only have a right column (arialist, binarius, brick fusion, nimble) - so there is no side-post-only problem as all blocks stay at side-post when moving them.
• 8 have major bugs (afterburner, anomaly, formal_white, leatherbound [very strange!], magazine [very strange!], serenity, splash, standard)
• 4 work halfway fine (base, canvas, boxxie, formfactor) [because they do not allow the docking of blocks!]

[I have attached the results as .xls file!]

We have a big amount of bugs and strange behaviours.
We are sure that these are not only theme issues.
We will need the help of the core developers to FIX these issues.
