Dear all, I am having some performance issues regarding adobe reader, but only when running multiple instances. Opening a single, relatively small pdf ( 418kb ) works perfect, but adding to the list of open flies another very small file ( 102kb ), the cpu usage jumps to cca. 53% mouse movements become jumpy and the cooling fan goes nuts. Nothing helps until the second file I've opened is closed. Closing only the first instance doesn't help at all.
This happens with any two files I've tried. Large, small, graphics or not. Hardware is not the issue.
