First of all, I must apologize for my poor English, I'm French, but I usually find better answers on English websites.
This is my problem:
I open a new file in indesign (I create completely a new one), place some elements inside.
And now each time I want to change a colour, it doesn't work... I need to press "SHIFT" button and click on the color in the palette, in the same time... or the palette react as if the color is not clickable... is there something I've made wrong ? A new parameter in Indesign ? (I've just made the installation of Indesign CC 2014)
Thanks in advance for your answer... it became a nightmare to create a layout now.
Already found a beginning of answer : for info, I got an iMac with a second screen: Apple cinema Display.
The palette was on my second screen... and it seems that when I put it on the principal screen it works again...
If someone know why, that could be helpful.
