Problems with Java version

Hello,I am having some problems when trying to run some SCORM learning objects that I have created with Lectora in BlackBoard.The objects are SCORM, and when uploaded to Blackboard 7.2 run fine in the viewer window on my computer and laptop (which have Lectrora v 2008) installed. I have the latest version of Java installed When I try and run them on other computers in IE 7 and with the latest version of Java, some run OK and some say "An applet on this webpage requires a different version of Java". They open another viewer window, but won't run.The objects wont run at all in Firefox (player window opens, some text, but no graphics).I suspect this is a Java error, but why do they run on my computer in IE OK, but not on another computer (same setup) where Lectora is not installed?Please help!Regards,Jon
