I have a perennial difficulty for the RHP site that has become slowly worse over the last few weeks. I have Performance Monitor running background and there appear to be a lot of memory leaks, which result in more and more page faults and the iexplore process just growing in size until the system freezes. It seems that switching pages doesn't always release the CPU because its indicator line drops visibly when I move around in other sites, but not always in RHP. I'm a technical ignoramus with an 800mhz CPU, so this problem may not be a problem if you have lots of free CPU. Does anyone have any helpful ideas for things I can try, apart from constantly closing and reopening IE? I'm planning to turn this machine into Linux/Firefox soon but can't do it yet for other reasons.
