I made a course with a modified master slide with Courselab2.4 and after viewing module or publishing I am getting a message box after I clicked on "Start Module" I got an Information box.
That is showing "Callmethod:003_textbox Constuctor'g_oSlideFrame' is null or not an object."

After clicking "Ok" it is running fine.
Tell me what I should do to overcome the problem.[:confused:]

Hi, Anirban,

This alert means that Textbox object is trying to create itself before the current slide is created. Perhaps you are using textbox object on the master-slide and some actions associated with it?
