Have windows 8.1 -- everything is always updated to latest versions.
Problem: Taskbar suddenly appeared as double height after awakening laptop from sleep. I can't figure out how to fix it.
Restart does not fix
Taskbar is not locked. Same problem with or without auto hide.
Double arrows can make taskbar higher, but will only shrink it to the double height, but they still allow expanding or compressing the horizontal area for the icons.
A few of the dozen or so former taskbar icons are missing.
All taskbar icons are their usual small size, except for the Programs icon, which is double size (maybe that's the problem).
Additionally, the icons for running programs are now displayed at about 4X their width and include text. (Icons for non running programs are their normal small size.
