“Multiple Signature” solution integrates to GroupWise toolbar, email toolbar and run menu. We think the run menu integration is causing the problem when Intellireach solutions installed. What are the integrations of the solutions provided by Intellireach?
Another thought, may be you can disable the run menu integration of multiple signature or other applets. You can change the applet integrations using Formativ Studio or Creator (Open Formativ IDE – select the applet – Click Integrations tab – uncheck “This applets appears on the run menu” option).
