Hi Folks
Just to let you know that I have finally succeeded in uploading my tree
No thanks to GR who have still not replied to my email......
In case anyone else has the problem I did - no response when clicking on the
Import file button - the next window is apparently a popup, so if you have a popup-blocker enabled, nothing happens .
I must admit I didn't know I had a popup blocker enabled, but I do now

Now to wait and see whether all the zillions of hot matches I discarded reappear the next time GR refreshes the Hot Matches (should be any time now?). In case anyone is interested, I will post the result here....
Best wishes
Angela
