Thank's Gary,
I'll change my code for your exemple.
And you are right, I meet with my code a hard problem one time in SC
In my previous code I added a pause of 0,25 seconds
The problem is very strange, SC seems to zoom screen and power increase again and again.
Very strange.
But SC is a beta version, no hoops, may be alpha version.
Then I'll try only repeat code and put a little pause between and try a less pause with 0.05s
I'll give you the result if any change....
Tanks again
