So Frustrated, Need HELP

I have no clue what to do anymore with Dallas. As I said before , she goes nuts when the mailman comes. But, for the past 2 days, she never even realized he was here. However; today, she realized it and all hell broke loose. I had her in a down/stay position waiting for when he came (I saw him at the neighbor's house) Dallas stayed until she saw him through the window, she jumped up, darted to the window (which was open) jumped up on the screen and her legs actually went through the screen, it happened so fast, all I could do was grab her and pull her back. I'm sure if I didn't pull her back, she would have jumped out. I think we scared the daylights out of the mailman. BTW, 2 weeks ago she jumped up the opposite window and scratched my table, knocked over the lamp and tore down the blinds. I don't know what to do with her anymore. Oh, and hubby blamed me for it all! HELP!!
