Thanks Erel,
Sorry it was wrong forum, and I did say I was a bit rusty. OK that's what I thought was happening, and yes I am re creating the layout, but that does raise a bit of concern, are new versions not backward compatible with older programs? I seem to remember a similar scenario a year or so ago when something I was working on stopped compiling after an update. In this case recreating layout is trivial, but I can forsee more complex programs being a complete pain to recreate. What is policy on updates? and is there a guide to what changes with every release in terms of impact on existing code. Perhaps I need to save a complete environment for every project with all Java environment saved, and not just update to the latest with every release.How do other users handle this?
Thanks for your prompt response, despite how much you seem to have grown you are still replying in very quick time
