Just to see if those bugs were because of the comma config, i put commas back. And those zoom and keyboard problems disappear. Problem: if i save it with commas, it will mess up the whole thing. Now i'm configuring back to points everytime i save it.
That's so very strange.
You see, my local configuration is a comma, because we use commas instead of points. While my Windows is in Portuguese, my Sketchup is in English (The translation is so rubish, it pisses me off). Do you think if i change my sketchup language to portuguese, those problems will disappear?
