Thank you Danzil. I have the OP Windows Vista Ultimate with the 32 bit system. The Adobe Flash Player is the 'latest' one. I have read some blog's and they admit a problem by downloading the Youtube Videos but not only them, it applies p.e. also for the small films on other websites (newpapers as an example). However no one has up to now been able to give a solution.
Lots of good wishes for you and your spouse........don't be afraid !!!!!!! I am married for 38 years to the same wonderful man ;-)))
Take your time for responding...........
Antonia
