An eagle-eyed user has spotted that if a Modify is run inside Select using Double Click (for any Draw objects, Cornu and Bezier) and is not ended with a Space or Esc, but instead interrupted by selecting a different command, the Modify will not be logged in Undo and the altered track may not immediately redisplay but go hidden. This is a bug that we now have a fix for, but for 5.1.2a right now, it is good practice to always end these modifies with a SpaceBar push (or Esc to cancel). Adam

Because of the importance of one bug in particular (not being able to set current layer) we have just released a V5.1.2a and replaced the builds for OSX, Windows and Linux in the SourceForge library. There were actually five bugs addressed in the hotfix - * Error in setting current layer. Bad Message and display shows the wrong layer as current. * Load of a checkpoint file does not refresh layer list. * PDF/PS/SVG print text fails if the text contains non-UTF8 text (like a degrees symbol) * PDF/PS/SVG print with Ties == None and Labels on results in unwanted lines added * Some Linux distros waiting for 30 secs during start up on splash screen There was also a little improvement - * Layers Lists now indicate with a "*" if the layer is frozen and an "m" if it is a module in the layer lists, as alternatives to "+" (has contents) and "-" (does not). * Manage Layers now updates the main window and lists immediately if the layer attributes for "hidden", "frozen", "module" or "button" are changed in Manage Layers. You can download the updated versions, they will show a V5.1.2a version number (at the top of the screen).
