All sound completely reasonable suggestions and targets to me. Black screen has disappeared - yippee ;o) For info to those interested I passed the driving assessment for ECA with flying colours which shocked me so much (having followed the past history of our dear blogger...!!!) that I answered the completely ridiculous questions with such flipflopiness that they 'refused' me at the interview stage. Gutted, but hey c'est la vie - they don't know what they're missing... and I'll try in another county... Take care y'all
