So despite using a fully updated version of adobe on a corporate licence, I too am having the same insane issue of overlapping text when editing a pdf.   It's actually impressive and amazing that Adobe manages to perpetrate bizarre and inexplicable faults like this (like the one where numbers are rendered as symbols) and not only are users in a situation where multiple updates of the software don't solve the issue, we are trying to troubleshoot solutions as Adobe themselves can't resolve it, whilst charging our companies through thbe nose for this appalling software.  It's so atrocious it's incredible, a sort of software version of Thames Water's level of management competance.   I cannot wait until there is a viable alternative! ...

Thanks for the solution, which worked for me. But I can't help asking myself: why?

Like switching off Protected Mode at startup and Protected View, which slow down the whole program to a snail's pace.   If we want to enable these options, for whatever crazy reason, LET US DECIDE TO DO IT. Don't force it on us. ... View more
