Hello Right click
on a blank area of the desktop.
Select "Arrange Icons By
Do you have a check mark next to "Auto Arrange
A check mark next to "Auto Arrange" will cause an icon that is dragged to spring back to where it was when trying to move it from one place to another on the desktop, but it should have no bearing on adding an icon to the Quick Launch bar.
Now, regarding trying to drag it to the taskbar...
do you mean that you are trying to add that icon to the Quick Launch
When you drag it to the Quick Launch bar, you left click on the icon, continue to hold onto the left click, and drag it.
As you hover over the Quick Launch bar, do you see an I bar cursor (shaped like the capital letter I) in that spot on the Quick Launch bar where you intend to drop it ?
Are you letting go of the left click of the mouse when you see the I bar cursor ?
I don't think a locked taskbar will cause that.
I just tried dragging an icon to my Quick Launch bar, and was successful in dragging/dropping it onto the Quick Launch bar.
I tried it with/without a check mark next to "Auto Arrange", and with the taskbar locked/unlocked.
I am unable to recreate your issue.
