After a court ruling, Microsoft has altered the behaviour of Internet Explorer towards Applets and other ActiveX controls.

The changes affect only ActiveX controls which are directly embedded in the HTML page. From now on, users of Microsoft Internet Explorer who want to interact with these controls, including Applets, will see the message 'Click to activate and use this control' and will have to click to proceed.

This is clearly not desired behaviour, but fortunately it can be avoided. The solution is to use an external javascript file to add the applet tag to your HTML page dynamically. Applets added in this way are not affected by the changes.

From version 1.5.0.209 of Blaze 3D Studio, there is an option to create this javascript file automatically when you create the HTML deployment files. This option is selected by default. The javascript (.js) file which it creates is referenced from the HTML page and should be deployed along with your swfs and other resources.

This javascript file is always the same, and so can be shared between projects. If you want to do that, you will need to update the HTML to point to the location of the shared javascript file for each project.
