Does anyone here still work with traditional connector for CATIA V5?

My question is about best practice with Enovia and CATIA V5 files from connector (not PLM services). Dashboards brings a lot of fine Enovia apps, which works also for these objects, but not in Internet explorer. So for Derived outputs and some other functionalities, which needs Java applets user has to use IE, but when you go to Dashboard, lot of things doesn't work in IE and you have to use Chrome or FireFox. What are your experience with this?
