Ever since WordPress changed the design of the dashboard I have had all sorts of problems doing something that would normally take me a couple of minutes. I am still having problems with most of the features from uploading images to links to videos on youtube.
If you ask me I think WordPress has made a mistake with this new dashboard. I am certain there are a bunch of bloggers that are having the same problems posting their material.
Frankly WordPress should do what Bill Gates is doing with Vista, DUMP this new dashboard and go back to the original.
