We’ve got a fix coming in 7.8.1. In the meantime, we did build the IA Labs PDF Viewer module for 7.8 so you can convert your old windows to the new Reporting PDF-Viewer.
Note: We do not recommend running this viewer long-term as it may result in dependency errors with Reporting in 7.8+. However, it should allow you the ability to open designer Windows that have IA-Labs PDF components and let you copy settings, bindings, etc. Just uninstall the module when you are done updating your projects.
