DRPsu11 & "ESC" command

[vampire4revenge]

Dear Developers of DRP su 11,
recently i find a problem with DRP su 11.
I have windows 7 Ultimate 64bit and every time i open DRP su 11, something "inside the code" send to the computer "ESC" command, so i can't view any dialog box, ex. RightClick Menu on Desktop and any dialog in windows and programs.
I want to ask you, why it's happen?
Sorry for my bad english

Thank you for your time!
