Hi bs2,

I think maybe you need parental supervision with your project. "Set_parent" that is :wink:

I found this code in the forum and tweaked it so that the 'cover' object can't be move by the user and I changed the background color.

You can remove the text line and change the color as desired.
You can size and position the window as desired. If the window that you want to obscure is moved this will follow.
If the window size is changed, you'll have to deal with that.

; e.g. run an internet explorer window and go to the page: "about:blank" so that is the start of the title text
;   then run this script and it adds a gui window onto the internet explorer window.
; Some programs, such as notepad and calculator, don't seem to work properly with this technique.

Gui, 7: Margin, 0, 0 

Gui, 7: Color, red

Gui, 7: +Disabled +NoActivate +NA -SysMenu +border -Caption 
Gui, 7: +ToolWindow ; -Caption ; no title, no taskbar icon
Gui, 7: Add, Text,, This gui is stuck to the parent... `nbut I haven't programmed it to do anything `;-)

;Set_Parent_by_title("about:Tabs", 7) ; can be done before or after showing the gui
