I recently started using Eclipse Juno (4.2) on Fedora Linux. In prior versions of eclipse I could simply click and drag a source file name to the edge of the screen and split my window with the mouse. Now when I click+drag Eclipse brings up some green outlines and I can't figure out how to accept the change without hitting Enter on the keyboard. Does anyone know if its possible to bring back the prior behavior where the mouse can do everything? Thanks!
Edit: Sounds like there may be a bug in Eclipse, at least when using Fedora 17 64-bit.
Now you have a green rectangle that represent the area that will be occupied when you release the mouse button, however the procedure still the same you have to drag the editor and drop the editor in the desired area ...
Just move the mouse with the left button clicked and you will notice that the green rectangles change and when you have a rectangle with double borders you can release the mouse button ...
