Yep, the title says it all.

The reason is that my programs topmost-window-layer-behavior interferes with the drop-target behavior of the chrome web browser (and likely other programs), with regards to peeling off tabs and dropping them on other instances of chrome.
(my program is this btw:[^], you see it's violating windows-design-guidelines by staying topmost despite everything you can throw at it, which leads to the current problem which i'm trying to fix :P)

[My current way of dealing with this problem is i detect when a person is peeling off chrome-tabs and literally hide the overlay until the point when they release the mouse, and naturally i want to solve this problem correctly to prevent interference with other programs which i'm not aware of]

And right now i'm assuming that the solution will be to to make my program transparent to WindowFromPoint, and possibly other windows discovery methods like EnumWindows.

you mean get the window from a point, if there are for example 2 windows that overlap in a certain region get the one being the top most window?

Per the documentation, WindowFromPoint won't retrieve a disabled window. Have you tried just disabling the window you wish to "hide"?

I set the WS_DISABLED flag along with other flags in a CreateParams overload. (I'm gonna enhance the question cause it may be that i'm on the wrong track with this goal)
