Hi,

Thanks for your response. Did you try with Windows Copilot or Copilot in the sidebar in Edge.

Both, also windows in sidebar won't open to full screen, despite exhaustive measures.

Hi,

Thanks for your response. Do you mean is window in taskbar? Please try pressing F11 to toggle full screen mode and check again. Also, try to repair your Edge in Windows Settings > Apps > Installed Apps. If your issue keep persists, please send feedback via Microsoft 365 Copilot app · Community.

Hi,

Can you please provide more information about it? Do you mean your Edge cannot maximize, or the Copilot window in Edge cannot open in fullscreen mode?

No issues with maximize or opening in full screen mode, updated Windows, Edge, Intel driver & HP Support Assistant software & drivers, currently using this work around: Left click & hold arrow at top of scroll bar, till scroll bar reaches top, this enables; HOME/ END, PG UP/ PG DN & UP/ DOWN arrow buttons.

Problem persists but, now works faster (gradually getting better/ more functional) once enabled, via using this work around: Left click & hold arrow at top of scroll bar, till scroll bar reaches top, this enables; HOME/ END, PG UP/ PG DN & UP/ DOWN arrow buttons.

Hi,

Thanks for the update. The issue still persists, but your workaround is helpful and matches what other affected users are seeing. please send your Copilot behavior to feedback hub by clicking Window + F. This behavior may gradually improve over the next updates.

Answer 2

Hi CHRIS AMBROSE,

Thanks for reaching out, and I’m sorry to hear Copilot isn’t responding to any scroll actions. Please try to maximize Edge to see if it helps to temporarily bypass the issue. If already maximized, resize the window manually by dragging any edge and then restoring it.

Since Copilot runs inside Edge WebView/Edge surfaces, cached UI data can break scrolling behavior. Go to Edge > Settings > Privacy, search, and services. Under Clear browsing data, choose Cached images and files > Clear. Also, click on Reset settings and choose Restore settings to their default values > Reset

A previous Q&A thread shows scrolling issues when an extension interferes with Copilot’s container. Try toggle off all non‑Microsoft extensions and then restart Edge

If your issue persists, please try press Ctrl + Shift + C and click the empty space under the chat box. Press Del, then Ctrl + Z. This resets the content tree and restores the scrollable region.

I was able to fix this (at least temporarily - we'll see how long it lasts) by clearing the cache as suggested AND Settings - Accessibility -> Turn Off Custom Scrollbars = ON.
