What happened to dragging the trade bar ?

[Mese]

When traders used to arrive all I had to do was drag and hold my mouse button by the item I wanted to buy or sell and the amount would increase or decrease .... now I only have the option to either sell all , or manually click one at a time , which if you have over a thousand potatoes can take some time

What happened ... or is it just me ?

You now also have the ability to type a specific number to sell.
