Adding a character in a block of text slightly increases spacing for next line so making the text block disjointed.
Even deleting a single character and then typing same character back in increases line spacing. However inserting same character by undoing deletion does not affect line spacing.
This is a common edit I do in PDFA V4 to update page number references without problem.
Excess line space is not acceptable in V7.
Problem did not occur in version 4 (or at least I thought it was V4, but about box says V188.8.131.5251)
I'm unable to us V7 until this is fixed.
Anybody any ideas?
