Troubleshooting
Why FusionViewer exits automatically when I try to switch display mode?
Current FusionViewer executable is Windows Vista compatible. But due to the fact that DirectX is chosen by default on Vista system with an ATI graphic card while we are using OpenGL to perform the rendering, there is a bug which disables the view mode switching. One of the possible solutions is to start a new application window if you want to display the images with different layout. We are working on this issue and hope to resolve it in near future.
Why FusionViewer doesn't start when I double click the application icon?
First of all, please make sure you have Java Runtime Environment(JRE) in your computer. If you do, please check the JRE version. For Mac OS users, type "java -version" in Terminal. For Windows user, please browse to C:\Program Files\Java folder. Current binary file was built on JRE 1.5. If your JRE is an older version, please update it.
I have JRE 1.5.0_10. Why I still have problems to run FusionViewer?
If you get an error saying "java.lang.reflect.InvocationTargetException", you are probably using JRE 1.5.0_10. The JRE 1.5 patch 10 for Windows XP is not compatible with JOGL library, which is required to run FusionViewer. Please switch back to JRE 1.5.0_02, JRE 1.5.0_04, JRE 1.5.0_06, JRE 1.5.0_09 or wait for next JRE release.
