outlook is blocked

Hello, the problem is the following ... When I execute the command:

this.mailDoc({ bUI: false, cTo: "apstory@example.com", cCC: "dpsmith@example.com", cSubject: "The Latest News", cMsg: "A.P., attached is my latest news story in PDF." });

Notice that the window minize button does not appear in the image. Why is this due?

The window that emerges from outlook is blocked and I can not return to the tray to enter and open other emails to complement the information. please help.
