Why is Draw constraining drag operations to horizontal and vertical?

Up to version 4.4.0.3, Draw would allow you to freely drag objects around the page. If you wanted to constrain the drag operation to horizontal/vertical, you could hold down the key. Now it seems to be reversed, so I’m having to constantly hold down . I need unconstrained dragging the vast majority of the time, so this is really painful. Was this a deliberate change? If so, is there a way to toggle it off?
Version 4.4.0.3, EN-GB, Draw, Mac OS 10.10.2 English (UK)

Tools->Options->LibreOffice Draw->Grid

“Snap position”, disable “When creating or moving objects”

That option is turned off. The problem occurs whether this option is on or off.

It appears that this was a bug. I just downloaded the latest version (4.4.1.2) and this problem is gone.
