Windows 7 Question about autoplay and files in explorer

Hello,

I just recently installed Windows 7 Ultimate x64 on my PC and I have couple of questions regarding it:

1. Next problem is about putting one file below or up the other one in Windows Explorer, for example:

File1.txt
File2.txt

When I try to drag and drop File1.txt below File2.txt so it looks like this:

File2.txt
File1.txt

I just can't, it dosen't work. But on my desktop I can do it without problem. Any way to fix this or workaround so I can freely move my files in Windows Explorer?

2. I'm having some applications when I run them in lower right corner, for example : "Windows Live Messanger" and some applications like "SlySoft AnyDVD". I was wondering, why when I one-left click "Windows Live Messanger" I get his options like I did right click on him, while when I click "SlySoft AnyDVD" it opens the whole application just like I would like it? Only when I double left click "Windows Live Messanger" it opens me whole window of the application.


Thanks!
