On Linux you should have 2 clipboards.
One  is automatically assigned, if you select text. It is used for 
pasting via middle mouse button. (it only reacts OnRequest)

Afaik there isn't an option for that.
This is the first time I hear that this replaces the other clipboard....

See TCustomSynEdit.AquirePrimarySelection;


Unless something happens during dragging... (I could not find anything 
in the code from a cursory look)
If you just select the text, and then do ctrl-v, do you get the original 
clipboard, or the selection?

If you use trunk, you can move lines (or selected lines, or even random 
selection) up and down via keyboard.

   ecMoveLineUp:          VK_UP,[XCtrl, ssShift, ssAlt]);  // or 
selected lines
   ecMoveLineDown:     VK_DOWN,[XCtrl, ssShift, ssAlt]); // or selected 
lines
   ecDuplicateLine:        VK_INSERT,[XCtrl, ssShift, ssAlt]); // or 
selected lines

   ecMoveSelectUp:      VK_NUMPAD8,[XCtrl, ssAlt]);
   ecMoveSelectDown: VK_NUMPAD2,[XCtrl, ssAlt]);
   ecMoveSelectLeft:     VK_NUMPAD4,[XCtrl, ssAlt]);
   ecMoveSelectRight:  VK_NUMPAD6,[XCtrl, ssAlt]);
   ecDuplicateSelection: VK_NUMPAD0,[XCtrl, ssAlt]);

(You can also add to the clipboard, collecting content from diff places. )
