My time sheets are very simple A4s - nothing fancy going on, no master page items, no different sizes - text still disappears.
The limited undos doesn't effect me all the time, but when it does it is a pain.
I hope Adobe are throwing everything they can at this - I'm not sure they have a handle on how much time this is costing us. I'm easily losing my monthly fee for CC in buggering around. I've been with the CS Suite since day one, happy to leave Quark behind due to their shoddy attitude - Adobe; Don't go the same way!
