I've been here years, and had over 3000 posts,... now I'm suddenly a newbie again with 5 posts?
I've not been naughty,.. no ban or e-mail from admin,...

I haven't a clue, but if you want advice on how to use a squeegy, go to Youtube and do a search there. There's loads of clips, some pretty decent, of people demonstrating the correct use of the tool.
I personally don't think anyone is a decent window cleaner unless they can use a squeegy, but that's only my opinion.
And welcome to the forum.
