Prosteel windows missing

Hello Long Jun Deng,

It looks like, you are working with multiple screens and switched to your main screen. And due to that the dialog opened in other screen, it remained there only. To get rid of this you need to delete *.Ave files from Personal wndsve folder. Refer following link to resolve this issue.
