These are known issues with Designer 0.4.3  

* On the Property Editor: You cannot change a value and then click to another
  window/frame without first pressing enter. The value will revert back to
  the original because one of wxPython's focus listener isn't being called.
  Not sure if this is a limitation of the way we implemented the Grid editor
  or a limitation of wxPython.

* Designer currently redraws the entire layout screen whenever a property
  is modified and whenever an object is deleted or modified. This may
  make designer run noticably slow on older computers.

* Designer loses custom xml encoding= attribute and defaults back to utf-8.
  If you manually specify in your GFD file, for example:
      <?xml version="1.0" encoding="iso-1859-2"?>
  then save it, the form will be written as:
      <?xml version="1.0"?>
  This will affect our international customers.

* You cannot delete an object (Page or Block) as long as it has child 
  objects;  i.e., to delete a page, you must first delete all blocks and 
  labels.

* Wizards have a few issues: 

    * Running a wizard and then running the wizard again without first 
      exiting will cause the selections from the first wizard to reappear.  
      This is mostly an inconvenience -- it shouldn't cause you to crash. 


The following aren't technically bugs, but may bite none-the-less:

* If you hand-edit a form definition and comment out sections using
  <!-- -->, then open this form definition in designer and save, you
  will lose your commented sections.  This is due to designer's XML
  parser which does not save XML comments.
