Just wanted to know if anyone else has run into this problem.

Some software has been installed that either updated a DLL or modified
the registry to cause the Explorer to crash when doing drag and drop
with multiple files.
If you have seen this what software is causing the violation?

I really do not want to reinstall all the software again.

If you want to email, strip off the +nospamjunk from the mail above.
Thanks in advance.
