Maybe computer code is like jelly, and it needs to set.
The code GF downloaded yesterday and had trouble firing up worked first time this morning with no attention from the Gorse Fox other than pressing the key. Bizarre.
Good work day. GF has to deliver some cut-down course material over the next day or two, so he has spent the day going through in advance to ensure he is familiar with the flow. Heading up to Surrey for the next couple of days.
