There appears to be a minor bug in Log Viewer (TI 8.763). If you configure the columns so that the log viewer displays # Number Type Date Time Message It is fine - i.e.#Number, Type, Date, Time, Message are displayed. However as soon as you move message up (so it appears further to the left-hand side) no columns after it get displayed. For example : # Number Type Message Date Time only displays #Number, Type, Message. Date and Time do not appear.
