Scripts interfere with voxel placeing and removeing


Seen it yesterday and today again. after playing with some example script like fallingsand.js
If that script is running or where running i cannot remove or place voxels. The voxel appear or disappear. but after 2 seconds the vanish or come back. when i remove the script from running and then restart interface.exe it seems to work normal. It need more testing, but its the 2e day this phenonem appears.
