Delphi 2009 - TeeChart 2010 - with full source...
1. Start Delphi - Start a new VCL Project
2. Add a TeeChart to the form
3. Add a new Series - TreeMap
4. Edit the Series - Go to Export - click on asJPEG - and then Preview.
At that point Delphi Freezes - and the screen greys out (As shown in the image below). I can duplicate this over and over

This seems to happen with other series and other export types as well.
