When I search on the site for an alternative number the results come up as usual but only remain visible for a second then all results disappear.  Anyone got any ideas.  This has only just started to happen.

jonwilly, please let us know how you get on. Is it or could it be caused by Skype and have you solved the problem and if so, how?

This will help others with the same query. If you have got some useful advice, then post on the thread jgxenite linked to so as to keep all the information together.
