mobutu: I just started adobe pdf, it literally took like half a second to start it up.
rtcvb32: Do you have an adobe background pre-cache-loader that you see sometimes with office programs and others? Maybe if it's cached beforehand...
But i've always seen it run horribly slow.
Adobe Reader has always been a POS, if it isn't starting slowly it is a buggy affair. I much prefer SumatraPDF, lightweight, just works.
That being said, the Windows 10 PDF viewer (built into Win10) is pretty damn good. So, that's really enough for anyone. On Mac the built-in PDF support and viewer on OS X is far better than the trash from Adobe.
There's just no reason to use Adobe Reader, except to say: I use Adobe Reader.
