I have been running 3.4.1 on LINUX mint. I imported a workflow with a BIRT report which ran sucessfully however once I closed that report the BIRT Icon disspeared completely. There is nowhere I can see to call up the report writer again. I deleted KNIME folder and re-unzipped a fresh copy of KNIME but I still dont see the BIRT icon. Are there some settings saved somewhere in LINUX I should delete in order to do a clean re-install? Its very frustrating. Can I suggest you have a menu item for the BIRT report writer as well as an icon?
