evening, after installing something via the Macromedia Extension Manager (while it might be unrelated) my activity monitor is showing some very strange issues. the process "mdimport" is eating 2/3 of my RAM, then it goes downt o 120kb, then back to the top of my real memory usage and CPU usage. the piechart is showing back and forth fluctuations non-stop. what does this process do? how to correct it?
