Eclipse open file using drag and drop

I have installed Aptana Studio 3.04 (a custom build of Eclipse for web development).

Now i just want to open a file via dra开发者_StackOverflowg and drop, but i can't - no area in the window accepts dropping a python file. Is it possible?

File -> Open file... - works perfectly. I use Kubuntu 10.04.

Looks like you have to have a project open to be able to open a file via dragging.
