I'm using IE 11 on my Toshiba laptop that's running Windows 7x64 SP1. It has a third-generation i3 processor, 750 GB hard drive and 16 GB of RAM. After I use IE 11 for a while the memory usage keeps increasing as the CPU usage for one of the Internet Explorer processes of which there are only 2 or 3 open. I tried reinstalling everything, turning off all add-ins, resetting Internet Explorer etc. nothing seems to affect the problem. I can't identify exactly when the problem began but I went back to the farthest back system restore I had in the problem still exists there.
Here's a screenshot from Process Explorer showing what I'm experiencing:
In this case the memory usage isn't excessively high yet but it climbs to about 1.4 GB before everything quits working correctly? The IR command program you see is an automation program to control an infrared system and the KB Pro software is an add-in for Dragon NaturallySpeaking. I've had both of those turned off for testing and it didn't affect anything.
Any help is appreciated!
