New DVAssist 2.0 now supports regional layouts. Instead of toggling strictly between US/Qwerty and Dvorak, it will toggle between whatever your active layout is (e.g. UK, Australia, French) and Dvorak.
The first open source version of DVAssist is now available. Runs on 95, 98, NT 4 & 2000. DVAssist is a Qwerty/Dvorak tray toggler that also can display the current layout in a stay-on-top Window. Great for training and use on shared machines.
