I have a problem when a guest places an order in the cart and dosent fininsh it.

The problem is the invtory goes down and down untill it reaches 0.

The guest that are doing this are trying to kill my bussiness and it hurts as the stock items are not reseting for unfinished orders.

Has any one had this happen?

Say i am a guest placing an order for a ramp my store has 10 and as a guest i order 10 but i dont finish it and the next customer goes to order a ramp and the store shows 0 ramsp when there are still 10.

How do i fix this.
