Another question I do have is how to "maximize" / "minimize" windows in Windows 7? For example here in Evernote I can't maximize the window and as it (as a lot of programs

) do somehow (why??) not properly recognize, that I put the Taskbar at the top, I can't change the position of the window!
Or which are the keyboard shortcuts I could work around this with?
Also another question would be why the single icons which I put into the (fixed) taskbar are having this "gap" between each other now in Windows 7, which they hadn't in Vista and XP? I find that a waste of space and would like to deactivate this kind of behaviour.
Thanks for your help in advance!
