Internet Explorer crash problem

[shandog1079]

G'day

Have had a drama with IE in recent times that seems to be intermittantly happening. The times I have noticed the crash have been when:

-Copying and trying to paste files in another location
-Accessing one or two specific sports websites (may not be related)
-Most recently - trying to drag a shortcut to Google Chrome into my quick launch icons. Will not allow me to do it!

The error for this last problem reads:
Problem signature:

Anyone have any ideas? I cannot think of any major software changes I have made that coincide with the issues.

OS: Vista Home Premium SP2 (32-bit)
Toshiba Satelite X205 laptop (intel cpu, 8700GT-M video, 4gb RAM)

Thank you for anyone who can help!
