If a sentence (in Writer) or a single cell (in Calc) contains multiple instances of the same word that is identified as mispelled, pressing "Ignore All" while spell checking hangs the program. "Ignore once" works fine, as does "ignore all" on the same word as long as the next instance is in a different sentence.
To reproduce, create a blank document and type two instances of the same mispelled word (eg: testa testa). Run spell check, press "ignore all" and watch it stall indefinitely.
I actually encountered this while spell checking a document with units on numbers, so that phrases like "nm" and "mL" appear many times. This was not a problem in 6.1.4, which is what I upgraded from.
I can confirm that this occurring for me as well, in an identical fashion.
