Hi Shai
There were problems when I used the provided MSI and .exe-files. Windows would consistently crash after logon, I assume while loading the layout. I'm running XP SP2 (32-bit) on a Intel Core 2 (64-bit), which might be the cause. The AutoHotKey-fix by hyperen didn't work for me. My workaround was to use the MS Keyboard Layout Creator and build an MSI from the Colemak.klc in the Windows download.
Keep up the good work.
