Open an Edge window full screen on the 2nd display.Connect a 2nd display and set it to 100% scaling.It should be possible to duplicate the issue this way: However, both IE and Edge (in Edge mode) correctly respect the screen bounds when opening these popups.Īfter a little more testing I think Edge might be opening these windows out of bounds only when multiple displays are present, and not all displays are using the same scaling (such as when an external monitor is connected to a laptop). At least in Edge, the window position is recorded in the preferences file, but this doesn't seem to control where the window will open next. It appears that I was mistaken in my assumption that IE and Edge were remembering the user preference. I went back and retested IE and Edge based on your second paragraph. Yes, my preference/expected behavior would be that Edge opens popups in IE Mode respecting the screen boundaries and if the window for some reason opens outside the screen bounds, there should be a way for the user to remedy this for subsequent opens. I suspect the IE engine is not reading either of these preference locations and just reverting back to a default value each time a popup window is opened.Īny insight from someone working on IE Mode? Or does anyone have a clever Kelly, It looks like Internet Explorer stores the location preference of its popup windows in HKCU>Software>Microsoft>Internet Explorer>Main>Window_Placement, but changing this value doesn't have an effect on IE Mode popups either. The value they get reset to seems to change depending on what DPI you have set. These position values do change when a popup window is relocated on the screen by the user, but they are reset if the popup is closed and re-opened, and the window opens in its original position. The popups we are calling basically work like this:Įdge looks like it keeps an entry in its preferences file to record the window position: Site also works fine in Internet Explorer. Running the same site in Edge Mode works fine.

When the user drags the window back onscreen, Edge does not remember the new popup window position preference for next time (whether or not the browser restarts).

Depending on the user's dpi settings, popup windows may open partially offscreen. I've had some users report some odd behavior with IE Mode popup windows that I've been able to duplicate.
