The "Save" function for saving a pdf is extremely annoying, it behaves like "Save as". And from googling I see this is "as designed"??? Why would you design the "Save" function to behave like "Save as". It's like 4-5 clicks to save one pdf! I see others complaining about this also. Why would such a big company design it this way one wonders..when every other program uses "Save" as they're supposed to.
