When using drag and drop the launcher bar reveals and will not hide unless I close the program.
Is their a fix?
Run this in a Terminal (Ctrl+Alt+T):
That works for me on Ubuntu 12.04.
Drag a desktop icon a bit.
Helps against the stuck launcher bar with Opera on a 32-bit system. Another solution would be to set the launcher not to hide in the first place (that's my solution for now). See How can I configure Unity's launcher auto-hide behavior?
There are also bug reports:
I ran into the same issue on 14.04. It seems this can happen with the four-finger slide gesture. If this is the case, simply do a four-finger slide to the left to slide the bar back into place.
Its not uncommon for the launcher to get stuck. Opening the dash with the Super Key seems to fix it for me and its way better than killing a program.
If you can reproduce it, you might want to post a bug report.
Same problem when using Netbeans (Java) : when I drag tabs to reorganize them, the launcher appears and gets stuck (ie wont hide anymore). Could not fix the problem, but found 2 solutions : - drag and drop Firefox tabs around - drag something to the laucher
I had the same problem after I moved icons around and opened the dash with the super key. I simply logged out then logged back it. Fixed it right up.
