There are all kinds of gotchas with mixing AWT and swing.  Try for  
instance embedding an AWT canvas into a JScrollPane and watch what  
happens!

In the application I developed (http://www.bioinformatics.bbsrc.ac.uk/ 
projects/focalpoint/) I had all kinds of problems because I was  
embedding AWT based ImageCanvas objects into a Swing based layout.  I  
ended up fixing this by making my own version of ImageCanvas which  
extended JPanel rather than Canvas.  You actually need very few  
changes to make this work and everything ran much more smoothly  
afterwards.
