Sales Order Entry Freezes when clicking accept.

Hello, 

We have recently had many complaints about Sales Order Entry freezing when users click accept after creating a sales order. We plan on restarting the servers this weekend but I am not confident that this will resolve the issue. I have searched both sage city and the knowledgebase and have not found any promising solutions. Has anyone heard of this issue/have any ideas what may be causing this? 

Thanks in advance!
