InfCloud 0.13.2.rc1 with Chromium (chromium-46.0.2490.80-1.fc23.x86_64).
Select the contacts manager.
Select a contact that has an email address.
Move the mouse over the email address field. At the right appears a black square with a white right arrow. Clicking it seems to have no effect. (Note: With firefox, it opens an email window. This could be a config problem at my side. Anyway...)
Click in the (last) email field. Type Control-V. A second, empty email line appears below the existing one.
This also happens with phone numbers, address lines, and so on. Only on the last line of a kind.
Note that we are *not* editing the contact, just visiting. The contact info is not modified.
Second, it is not possible to click in the notes (txtNote) field, so it is not possible to copy/paste anything from it (FireFox and Chromium).
