Sorry for the trouble. I'm sure we can help you to sort this out.
Does the problem occur if you have no documents open, and then create a new, blank document and work in that? (e.g. does it stop responding when you try to save)
Who manufactured your computer?
Do you have the latest updates for Windows installed? (e.g. Service Pack 1)
Thanks for your response. Don't know why I've not worked throught it before but the problem occurs when I add recordsets...the more complex the php code and the more datasets I add, the slower things get. So it's to do with interaction with my testing server (Xammp). It could also be an extension as outlined in Nancy O's reply. So will work through them.
My computer is Mesh but the problem has not existed since I obtained the PC and loaded DW. It has 'arrived' at some point, and I didn't take the trouble to note when!!
If you have any advice about problems associated with server interaction I would appreciate it.
