Quick Launch Toolbar

Play around with dragging until it's where you want it.

if you told us where you want it to be!

First, open a program (doesn't matter which, take Internet Explorer for example). It will appear now on the taskbar.
If I understand you correct; when you do Right-mouse > "toolbars" and then "quick launch", the Quick launch comes back left from the system-tray instead of on the right of start-button.
If this is the cause, just drag de Quick Launch into the direction of the start-button; you will notice that the open programs will appear now on the right of the Quick Launch, and this is the way it is by default. Hopefully this has solved your issue.

All the best!

Note: If you are using XP, you should click right-mouse and uncheck "lock taskbar" (if it's checked) otherwise you are not able to drag.

When you re-activate the quick launch toolbar it always comes up by the tray - from there you cannot move it. However, you can move the the other part of the toolbar where active applications are displayed. Click and hold the virtical tab (should be by the Start button now) of the applications bar and drag it to the right of the quick launch bar. You'll see the quick launch bar jumped to the left and settle by the Start button.
