Photo Levels Grey Point tool doesn't work when zoomed in

Pretty self-explanatory...

Create a "Blank photo", import something, zoom in a few times (for example, on the eyes - which are a sensible point for white balance), start the Photo tool, then the Levels tool, then drag the "Grey point" picker over the image. Nothing happens.

Hi Alexander,

It seems that when zoomed in on the photo nothing happens if you use the Black or White point picker tools as well. Would be nice if it worked when zoomed in on points of interest.

Might well be a bug because instead of zooming, for example, 2x you can temporarily enlarge the photo 2x via the info-bar and the picker tools will work. Once done, simply resize back to the original.

Well, of course it's a bug - it's just stunning how something this obvious can be overlooked in QA... (yes, I know, I complain too much)

Hi Alexander,
the levels tool colour picker works ok for me from 10% past 1000% following your method. Tried with black grey and white points with no problems.
Using Windows 7 64bit here.

Hi Peter,

Windows XP 64 here and only works at zoom levels below 400% (I think)...

It worked for me (Windows 7 64bit), but how are you zooming in? I use ctrl/wheel. When I right click zoom on a selected photo sometimes it starts up Photoshop, hence the wheel.

I zoom in using Zoom in / out keyboard shortcuts (for me, Numpad + / -)

To see if the problem continues with other zoom methods, you might like to go to options (shift/ctrl/o), select mouse and ‘zoom in or out’ for the right mouse button. Place your cursor where you wish to zoom and click the right mouse button. To zoom back out do the same while pressing the shift key. Or, if you never use the mouse wheel to scroll left or right, you could select the ‘zoom in and out’ under ‘mouse wheel movement’, and again use your cursor to aim.
