Windows 10 1803
MWG 7.8.2
IE 11
java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)
I tried on 2 windows 10 client machines using same jre version, same issue.
Using java-webstart or html5, works perfectly.. I can confirm java applet is enabled in my IE internet options settings.
