whenever on click action is placed in abutton followed by go to

Hi, royrana,

Action threads are not protected. Therefore one action can kick off the ground from another action (if they are launched in parallel). It may cause an error. For example, GOTO leads to erasing all previous slide objects from memory, and if second action refers to such objects, the error may occur.

Thanks for the reply.
So to how to place rollover action(mouseup and mouseout)and click action on same button simentenously.
2nd problem: the score sheet in quiz section is not working.
3rd problem : Attaching more than one flash programme in one package and using it in moodle as SCORM package is giving only one output of flash in moodle scorm course

Hi Royrana
If you take one of the standard navigation buttons you have the option of using the deafult image set for the normal mouse events. You can also change these to custom images.
So I've used a standard navigation button (for example next), customised the graphics and then changed the target for the on click event.
I'll verify this works in 2.4 later today.
