Issues with overflow:auto

[nuno12345z]

First of all thank you for your plugin it is feature-packed and very easy to use. However due to requirements of our software I needed to extend the functionality of your plugin, but I'm encountering two issues:

1- To allow navigation inside the grid for a big grid (24 hours, several schedules), using the sc_main_box div as:

sc_main_box { float: left; overflow-x: auto; overflow-y: auto; position: relative;

However when dragging items they work fine unless the scroll doesn't move, otherwise they tend to become unrelated to the mouse cursor position. Is there a way to fix this? Picture1

2- When two overlapping items are placed they correctly make the row bigger, but at the start of the row there is a blank space which is not a div, not a span, nothing at all. Can this be a consequence of having a 25h day (to allow post-midnight bookings?) Picture2

Thank you for your time
