Closing frustration continues...

Just heard from the lawyer that he's still waiting to hear from the owner's lawyer when she is able to come in and sign the deed over to us.  She knew about the August 1st closing date for about 6 weeks - why the delay?  Makes me very nervous.  Jim sent a response back to the lawyer asking his opinion into the delay, but when it boils down to it, I guess she's holding the cards at this point.
