My company laptop has a very odd problem with Windows Explorer. When i right click to show the context menu, and it had not been shown for a long period previously, the menu renders and within a second will start to seize the CPU and work it to the max. Everything slows down including my USB mouse response.

The context menu in my own personal laptop is far more complicated and cluttered than this machine's so I am wondering if there are some known problems with the way WE deals with its context menu?
