One of my Windows machines recently started experiencing the following behaviour:
When a windows explorer window is open (it can be the only window open on the desktop) but not focused, pressing the down arrow key brings it to focus. If it is minimized, it is brought to the foreground, no matter what the program currently in focus is.
We've tried
- another keyboard
- using software to check for hidden keyboard shortcuts,
- searching through the Registry for the string 'focus',
- googling for it, of course (e.g. for 'pressing down focuses window' or similar queries)
- asking in serverfault.com (closed as 'not sysadmin related')
- asking on http://groups.google.com/group/microsoft.public.windowsxp.general
- running a deep antivirus scan (avast), spybot, ccleaner. No relevant results, and the behaviour continues
- used process explorer's verify option on explorer.exe, but it gave no useful information.
- searched in TweakUI for anything likely
- searched the accessibility options
- tried setting and unsetting focus-follows-mouse inside TweakUI.
This issue appears on XP SP3, and I did try searching this group, but the problems I found were usually of the 'Explorer not focusing correctly' on something or other.
Has anyone encountered similar behaviour?
