"iexplore.exe - Application Error" - Help requested!

I was browsing the internet (using IE6) and I suddenly and surprisingly receives this error message:

"iexplore.exe - Application Error

The instruction at "0x7c931c6b" refrenced memory at "0x1fffffff". The memory could not be "read".

Click OK to teminate the program
Click CANCEL to debug the program"

It pops up every so often and is starting to get annoying.

First of all check you have script debugging turned off.

In IE go to tools > internet options > advanced > check disable script debugging (internet explorer) and disable script debugging (other).
