Lightroom 4.4 - crop aspect ratio not locked

I can reproduce it. With the padlock locked, dragging a corner to "flip" the crop rectangle works only as long as you do not touch the original border of the photo with that corner. As soon as you touch the border, the aspect ratio becomes variable and changes to "user defined". Sometimes also happens when touching the border with other corners than the one that is dragged.

This can be especially annoying when trying to flip a crop rectangle that is at maximum at two sides, because one will inevitably touch the border somewhere.

As long as all corners stay inside the original borders, the "flipping" works OK.

Win 7 64 Bit, LR 4.4.

P.S. Workaround in the meantime: The X key.

This bug bit me, today, too.

I have this too, I'm working on some event photos and it's driving me batty and slowing my workflow way down.

I am having this issue too. Really frustrating. It's really slowing me down and I'm on a deadline. Need a fix!

Karen, Use the X key to flip your crop until this is fixed.

...and if you suspect that the damage is already done to some photos:
Sort them by aspect ratio. Makes it much easier to find those photos with an odd aspect ratio.
