Finally I am giving it up.
I have to read different pdf, online, offline. So, as usual, the first choice would be adobe's pdf reader.
However, my Adobe pdf reader has been crashing like a crazy in windows vista. More than 20 times a day. I have to see pdf and adobe pdf viewer does everything except properly showing the pdf files.
So, finally I looked around to see other alternatives. For now Foxit reader seems to be good alternative.
I am hoping that it will not disappoint me.
