You're welcome, John. See DMcG's comment as well.

The number of new systems I have stopped or delayed the roll out on because they cannot be used in a number of circumatances is very high indeed. Occasionaly we would have to use the old phrase 'not supported' (doesn't mean it will not work!) on this browser or that kit. The old 80/20 rule ofthen applies. If it works 80% of the time with 20% of the effort, why spend another 80% effort to get it working on the other 20% !?!

I am long retired now but still have multiple browsers on Android, Windows and Linux devices to check out if one works where another doesn't. The ones I lack are Apple devices - Simply due to cost!
