I know, this sounds weird, but I have had trouble with it more than once and wonder if anybody else does too. If I have the DTS 2000 Package Designer open to modify an old DTS package, and then try to edit a query within SSMS, I can't use the delete, backspace or enter keys. What is going on If I close the DTS window my editing capabilities instantly return.

cant edit query when DTS 2000 Package Designer is open
