Header? Are you talking about clips, John? I'm talking about the area to the left of the track view where the i/o options, FX bins, arm/mute/solo, track name, etc are. In X1 I didn't have this difficulty moving the tracks around. It does work but I'm having to hover all over the place to find a very small area in the gray space that turns the cursor into the tiny little arrows that point up and down which allow you to drag the tracks into folders and whatnot.

I'm convinced this is some kind of graphics bug or incompatibility with my graphic card. The strangest part is I didn't really notice it in X2 until very recently. I did a whole project and this didn't stand out as a problem. I haven't done anything different to my system. It's just... weird. :-/

In the TV "track view" there are the clips pane and the track header pane. The track header is to the left of the clips pane. Its where the widgets are and the track title also the meter.  

To move a track you click on the the track header where the title is to the left of the clips pane and has all the widgets but you need to click an empty space adjacent to the title and hold then move the track where you want it. You should see a line indicating where it is going to.   

BTW to move a track to a folder select the track or tracks and right click on that same spot. You should get a drop down menu and in it you should see move to folder. Put your mouse over the Move To Folder and a folder or folders with show up click on which folder and it will be put into that folder. 

All the above is easier to do than to describe.  

Are you guys clicking on the title part of the track header? Not the title itself though.

 
As best as possible.   It's not the largest of areas though, so it can be a little finiky that way.   But even when it's not directly on the title area and instead on a blank grey spot, sometimes the track can still be "grabbed" and moved (I tend to do that often just by instinct). 
 

If you don't have enough space to get a blank area in the track title area move the window pane divider to the right. 

Ah... okay. That Move to Folder option sounds easier. Didn't know it was there. Thanks. 

Its a lot easier if you have multiple tracks.
