Hello,

I have been unable to reproduce the error taking the following steps:

- Open Eclipse
- Select 'New Java Project'
- 'Create project from existing source'
- selecting the folder: 'Examples\SWT\Features'
- Build and run of project.
- Clicking on 'Basic features' shows page with Chart and executable code.

Please confirm the version of TeeChart that you are using (release.txt file in the TeeChart installation folder). Is this the registered or eval version?

With thanks.
Regards,
Marc Meumann

I followed your instruction. Created new project and run as "Java application". Again when I select the "Welcome"->"Basic feature", application is vanishing and throwing same error.

Below is the version info.
