Hey guys, I have been using preview a lot for annotating my PDF's especially the highlighting feature. I came across this annoying issue ->Basically, the highlights in the PDF seem to fade with with time. For instance, when I tried to open a one month old PDF file the highlights seems rather faded compared to how it was initially. I did a google search and found that this seems to be a bug on the OS. I am running OS X 10.7.2 and can anyone please let me know if this issue has been fixed lately? or if there are any workaround solutions to this problem? Thanks in advance.
