You should be able to tab around the sand box screen which comes up. There is a drop down near the bottom which lets you choose what action to take. I think the options are to run in sandbox, cancel or run normally. Sandbox being the bottom but usually default option. There is then a tick box to get it not to ask you again for that application. Then go to OK and press Enter or spacebar (with JAWS only one works, can’t recall which). Sandbox basically lets you run a programme, and if all goes wrong it doesn’t actually make any changes to your system. I’ve never used it though other than as described abovabove.

I think it is involved with the Trekker sink programme. Apart from removing the Trekker programme how can I stop this happening. Thanks Brian
