I got a blue transparent screen in my sketch and I can not write or change the number or anything on sketch.
I get a massage : "The sketchbook folder no longer exist. Arduino will switch to de default sketchbook location, and create a new sketchbook folder if necessary. Arduino will then stop talking about himself in the third person"
I found it in C:\Users|MyPC\Document\ArduinoMust I move this folder to another place ?, where?
the transparent blue screen still stay too.
If I go to FILE --->SKETCHBOOK ---> can not open
I have tried to change to another folder but not lucked.
I had tried change: File-->reference--> sketchbook folder name.
I am not use external editor.
