Can't unselect objects in JOSM

[naoliv]

I don't know what happened with the latest versions, but it seems that there is a problem while unselecting objects in JOSM.

For example, if I select any node or way and then left-click the mouse at anywhere empty, the object keeps selected.

To unselect it I have to right-click the mouse (it opens a menu) and then click outside it.
It's also possible to unselect the object by keeping the left button pressed and draw a selection area at an empty place.
