While dragging and dropping in a quiz, the picture of the tile you're dragging appears in a different location than the mouse pointer.
Drag and drop still functions properly if you just ignore that the tile appears in the wrong spot while dragging. And the tile does appear the correct spot when you finish dragging it. It just feels a bit weird.
That might be impossible to fix. I'm not sure if you do any web development, but here's the explanation:
I'm using something called scale(), which literally scales up the quiz blocks. It's only done visually, though - all the elements that actually make up the webpage are the same size (in terms of flow) - so when you drag/etc, it's referencing the original size.
A *true* zooming system would have had to been added ..well...10 years ago, so I'm trying to do what I can with the structure I have at the moment.
