drag and drop in opera breaks launcher autohide

[Julian Taylor]

Binary package hint: unity

dragging an image or link in opera causes the launcher to appear and never disappear again even when autohide is enabled.
this is very annoying as after this the launcher covers large parts of all maximized applications.

this seems to only affect opera, drag and drop in firefox does not harm autohide.

just discovered that autohide can be recovered when drag&dropping something in thunderbird
or when drag and &dropping something in nautilus _AND_ pressing alt tab.

Marking this as a dupe of bug 728841. Discussion about the implementation and functionality of these dnds within unity can be found there.

I disagree a bit with the duplicate status.
while in firefox the launcher appears, it disappears again when you stop (I regarded this a feature not a bug).
In opera on the other hand the launcher never disappears which is a bug.

I can confirm the last post by Julian Taylor, dragging an object in Firefox causes the launcher to appear, releasing or dropping it, the launcher disappears instantly. In Opera, the launcher stays always on top of all applications, even if they are opened after the launcher has frozen in Opera. Opening Libreoffice in that case caused the launcher to disappear, but Opera crashed in that same moment.
