It might be related to your language - I am not certain how many Hebrew users we have. We are reaching the end of my day but, if it hasn't been tested by someone else by tomorrow, I'll check the Hebrew environment and see if it works for me (it will be nice to test a language I can actually read some of for once!). Do make sure you have PokerStars installed in English though.
Dirkvanb: Yes the Zoom HUD is just like the normal one - PokerStars writes the full hand history text even if you fast fold, though they are written in order so you may see bursts of data after longer hands finish.
