Drag and Drop in Course Pres: save, alignment and scroll bar error.
Hi there :)
I have been working on a Course Pres with 1 drag and drop on each slide (x16 slides). File attached.
Today the draggable items are moving after saves (they move about 20px in random ways). Sometimes they hide under the drop and drag canvas and I can't get them out in edit mode:(
I created this resource in Firefox - when viewed in FF, Chrome and IE the random draggables appear to have moved after each time I save it.
Additionally, when I view the same slides in FF/Chrome/iE - some of the drag and drop canvases have a scrollbar, which is not consistent across all browsers, but they are appearning when viewed in chrome (SEE SLIDE 10).
On a second note, when I go to save this activity, I get an error message saying "the content on this page has either been modified by another user, or you have alrteady submitted modifications using this form...and my changes cannot be saved..." I defintely do not have this resource open in another browser or tab or device.
Any help appreciated! Thanks for reading.
