> <param>after leaving netbeans open with 3 php projects and returning to
> this workspace on the next day, the ide ist horribly unresponsive (mouse over
> effects take about 4 seconds to appear, clicking menus and files is super
> slow too). exiting NB (either via window close button or via menu) closes the
> window, but netbeans keeps using cpu at a rate of 80% and ram usage
> fluctuates between 1.2G and 1.35G. this goes on for at least 10 minutes,
> after which i kill the process.</param>
