Dreamweaver CS6 crashing

I hadn't inserted any ID numbers in any of the cart items so am having to go through them and open from Server Behaviour and insert the unique ID. However, Dreamweaver C6 keeps crashing after every third entry. Is there a fix for this? The version of Dreamweaver is: v12 build 5808

I haven't seen this. Are you on PC or Mac? What do you mean by "every third entry"? Please be specific about the exact steps. If I can reproduce it I can fix it, otherwise I'll have to set up a screen sharing session to debug it with you directly.

I am having to go through the entire cart as I did not know that the ID identifier was crucial for the cart to work. So I have started by opening up the web page, going to Server Behaviour to go through the entries one by one. I add an Identifier and (such as ATTWN1957) - after I add three consecutive identifiers to three cart objects, Dreamweaver says there is a problem and it has to close down. If I save after each one, I can do ten before it decides to crash. Obviously with over 800 items this is extremely annoying. I didn't have the problem when I was actually entering the items to begin with, just now that I am updating them. Am using Windows 8.1 on a PC
UPDATE: I think I have found a solution to the problem: When I update the Add to Cart button with the identifier. Instead of clicking on OK after inserting the ID, I highlight the 'Name' field and then click OK - the problem appears to disappear! If it starts to go wrong again, I'll let you know. Thanks for your help with this matter
