Application error

[AD]

Hi everybody,

I have the following pop-up screen appearing everytime I
use the web:

msimn.exe - Application Error
The instruction at ''0x77f83907'' referenced memory
at ''0x009a4d1c''. The memory could not be ''written''.
Click OK to terminate the program.

Is it something to do with Dr. Watson, the debugger?

How do I correct the problem?

Thank you.
