Solution to you Question : It is one particular addon on IE which is causing a problem and inorder to fix it you have to reset IE
Step 1 :
Internet Explorer>Tools>Internet Options>Advanced>Reset
Step 2 :
Go to Control Panel and then access Internet Options.
Close all Tabs before you could try this as it would throw up an error and sometimes you might not be able to reset even if you've closed all IE Tabs or windows, so you need open task manager and end the iexplore process and then try resetting IE.
This will fix the issue.
IF this issue occurs on Word Processor then disable a few startup items which are not required especially the once from ATI.
Start> Type Run > msconfig > Startup
Restart the computer.
