Hi,
I have recently read the post (Client config file problems) regarding an error in the XML and noticed that it was a bug in the previous version of the client and would be fixed in version 1.7.6
Im currently running version 1.7.6 and this issue is occurring for me for the last couple of days.
I have attempted to resolve this issue by copying and altering from another client but after a while it clears itself and throws up an error.
I have 8 other displays which are all fine.
