Hello, I have some trouble with ScriptLab : I can't use the effect Levels in ScriptLab. When I try to, the loading bar goes instantly to 2/3 and never moves. Then I try to click "OK" or "Cancel" and Paint.NET have to restart everytime. All the over effects I tried work instantly. I tried to wait several minutes, but without success. I run the version : "paint.net v4.0.9 (Final 4.9.5848.30436)". (I tried with the older version v4.0.3, the same). Does Levels work for other people ? Thanks !
