Greg, thanks for the great tip on Firefox.There were dozens of warnings about 'align' elements, then eight errors including:- missing ; before statement for a toggle visiblity action- findWH is not defined- button489 is not defined- trivOnFocus is not defined- junk after document elementI'm kinda at a loss at how to attack these. If nobody here has any suggestions I guess I'll try calling Lectora support later today.ThanksJohn
