When I am in the DEVELOP module, every time I press OPTION key to alter parameters the COPY SETTINGS window appears, which makes the workflow really hard and irritating.
I've already tried to check system preferences, but it gave no result.
How could I resolve this issue?
Thank you in advance.
Try resetting LR's preferences: http://www.lightroomforums.net/showthread.php?25197-Resetting-the-lightroom-preferences-fi le-updated. When LR's user interface starts acting weird, resetting the preferences often fixes it.
Thank you for your reply.
Yesterday a support specialist connected to my computer and tried a number of things, including the resetting you mentioned.
Unfortunately, this did not help. What is more, I also experience the same problem on a different Macbook with different account. And it also happens with both OPT keys.
This is the list of things we've already tried:
1. Resetting settings via OPT+SHIFT on startup;
2. Creating a new catalog;
3. Deleting preferences folder;
4. Pressing option on a virtual keyboard;
5. Resetting all settings in System Preferences -> Keyboard pane.
The support specialist connected to my computer and pressed the option key on her computer, and it worked OK, so I think it is something with my keyboard preferences, though I can't understand, what it could be.
