but it's always ok when I use the menu to perform the operation.

the error message is

"Object reference not set to an instance of an object."

Could you please provide Steps(sample code etc...) to reproduce your issue?

Baoquan Zuo at 10/9/2009 11:31:24 PM -

I did. it seems that the error only occurs when renaming items in a package.

I can not reproduce your issue.

> 5. locate the cursor in the Test method, and press ctrl-shift-e
Could you tell us exactly where you locate the cursor?

sorry, it's so strange that I can't reproduce it again.

Ok, if you find steps, please update [Steps] area.
