Right mouse click issue

I'm connecting to a Windows 11 computer using RDP running the mode where I can directly click instead of moving the mouse pointer. When I press and hold to bring up the right mouse click menu, the menu appears, but unless I move the screen or zoom in or out, clicking on a menu item does nothing. It appears to select whatever is behind the menu. For example, when in Outlook looking at my list of emails, if I long press and select "Reply", it doesn't open a reply. Instead, it selects the message that was behind the "Reply" menu item. If I do the same thing, but zoom in or move the screen before I select "Reply", it works. If it matters, I'm running a custom resolution (1920 x 1200), so my Android device matches my computer display without resizing the desktop.

Thanks,
Rich
