Hi,
I am running an applet on different platforms (Windows XP, MacOSX) and different browsers (IE + Firefox for XP, Safari + Firefox for MaxOSX). I have encountered an issue only for MacOSX platform (10.5.2, it was already there for 10.5.0). Here is the scenario :
- I open a Safari browser and instantiate an applet within a web page. Everything works fine.
- When trying to launch a new page and so instanciate a new applet, this error occurs :
