BUG: Can't take off hold status

We have discovered a bug in 4108:

We use the hold status to designate tickets where we have provided info to the client, but are awaiting their response, etc. What we have noticed is that we are unable to take tickets off of hold! We are still testing the consistency of this, but we have plenty that are showing 'on-hold', even though the history shows it being taken off hold.

We would obviously like to see this fixed ASAP. We would also like to see some way to place a ticket on hold automatically (or with a checkbox) when responding to a ticket. For example, when a tech responds to a ticket, have a checkbox that says 'place on hold pending response'. Then it would automatically come off hold when the customer responds.

Urgent for this fix!
