As it is one that you would have no idea about what is causing the problem, Ol mate Murphy declares that you must consider everything!
Will be interesting to see if the customer dicides H or FY, or TFT...
oh yer, Forgot it was a premium, TFT, or FY or more likely NR, cause he didn't/may never see my post;) . Been in Tasmania for the last 10 days.
