Recurring fails with both Taskbar and True Launch Bar

As no-one has no idea what might be causing this taskbar quit and restart, 
I don't know if it's an issue with Windows taskbar, or with True Launch Bar. 

Here's something which might be a clue.
Right-click on a space in the taskbar => Toolbars 
shows
 
Address
Links 
True Launch Bar ...
Desktop
(ticked) True Launch Bar 
----------------------------

That unticked'True Launch Bar ...' leads to 
C:\Users\User\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch

Is this normal?
