I am a longtime user of Acrobat, but am just trying out Acrobat X and am having a lot of difficulties with the commenting. I am noticing that in order to continually mark changes in the text (using either the replace text or insert text tools) you need to click back on the buttons every single time before writing. In Acrobat 9, you were able to just start writing and your text would automatically replace or insert text where ever your cursor was placed.
Is there a way to get this back again in Acrobat X? Perhaps some preference/or setup option I haven't selected? It's driving me absolutely nuts....
Select a block of text and press DEL to redline it.
Select a block of text and press INS to blueline it, then just type your replacement text.
To insert text, just put your cursor at the appropriate place, press INS and type.
