This happens especially in Outlook in creating new emails, but can happen with any combination of windows, where a new window is created but comes up “in back” where we expect it in front. Steps:
- Run REGEDIT.
- Browse to: HKEY_CURRENT_USER\Control Panel\Desktop
- Open, or create and open, DWORD value
ForegroundLockTimeout. - Set it to zero, click OK. Default is 200000 .
- Quit and reboot.
