LR 4.4: odd behaviour when moving images in comparison mode

[dreed]

when moving images in comparison mode and zoomed in, if the moving hand ends up over the "other image" and I release the mouse button, the images continue to move with the hand as if the mouse button were stuck down.

is this recognised as a bug? and/or has it been fixed?

well, now I can't forcibly reproduce it, which is annoying!
