CHtmlView and JRE Plug-in Issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   For quite some time we have used Docking Panes combined with CHtmlView controls to put a multi-tabbed integrated browser into our application.  Sun recently introduced their "next-generation" plug-in which is enabled by default.  When using our application on Vista with this plug-in no applets will load in the browser.

An older version of our application before we created the multi-tabbed setup with Docking Panes works fine.  Also the MS example application which can be found here works as well.  This has led us to believe the problem may lie with the Docking Panes.

This only happens on Vista, either as a standard user or when UAC is enabled.  Running as administrator or running in debug it does not happen.  Disabling the "next-generation" plug-in also fixes it.  However due to deployment requirements for our software disabling is not a viable option.  We updated to v13.1.0 hoping the problem would be fixed but it still happens.

The following is the Java Console log and the page used:
