Everything is a bug in this latest update. Adobe DC is for "Destroying Careers". Slow, unstable and the sticky notes feature is the worst ever. I am reading and copying text from the sticky notes and this happens:
The yellow boxes shakes, like a vibration.
The text on it are over an yellow background and when you do the action: select + copy, it simply "enters" the text and replaces the background by a white one and you have to SELECT AGAIN. :(
When you finally discover that you have to select the text again, if you accidentally moves the cursor beyond the sticky note, the text gets UNSELECTED. And you have to SELECT IT AGAIN. :(
If the sticky note has a bigger amount of text, it replaces part of the text by a ... little box. Than you have to click again to OPEN the entire text. An than, the sticky note CHANGEs its place on screen. It makes you WASTE time and ***** your concentration.
Also the add Signature / Sign tool is VERY SLOW now. And it cannot manage multiple pages. Today I signed a contract of 8 pages and I had to enter and leave the Sign Tool only 8 times to place 8 signatures, one per page. Can't it be smarter and faster?
I got so mad today trying to use this "new" version of Acrobat DC that I could not continue without writing this comments. Hope you fix it ASAP.
