Actions Working Intermittantly

I am experiencing an issue with a course I created in Lectora that I am not sure how to resolve.I have a number of actions created as groups for various functions in a Lectora course (for instance, one such set highlights the next button when a swf file is done playing by swapping out the next button visiblity with one that has a highlight glow). The problem is that these actions don't ALWAYS work. And it is inconsistent.For instance, I have a text display that follows the flash narration. It is updated by a timer in Lectora based on the value of a variable. When a new text block is needed, Flash passes a javascript call that updates that variable and the timer code eventually switches the displayed text based on the new variable value. All of this is set to launch on page show, and there is an action to set the value of the text display variable to the initial value (Txt01).However, this doesn't always work. Sometimes I will have to reload the page to get the text to display, but without a reload will spend the first whole paragraph looking at a blank space where text should be (but play the course through from the beginning after clearing the cache and reloading everything, and the next time through it's fine. One more try and it's not again). This isn't only happening with the text display. Anything that's supposed to launch on page show or on swf done playing doesn't always work.Has anyone encountered this before? Does anyone have any suggestions how to correct this? I'm pulling my hair out trying to figure out where the breakdown is.Thanks in advance,Jeremy
