I'm not sure when this started (maybe since 10.7.3 came out?) but I've noticed that Microsoft Word is rather consistently getting up to 1 GB of RAM or higher even when I'm not doing anything that complicated in Word (text files without images, etc.). Anyone else noticing similar behavior? The only other thing I can think of outside the 10.7.3 update was a plugin that I installed (Write'N Cite from Refworks) which I ended up uninstalling after a couple of days because it kept causing crashes. Once I restart MS Word, the RAM usage goes back to normal. If I only close all the open documents, RAM stays up high. Any suggestions of things to look for? Or anyone else having similar issues?
