I'm on V11SR1,
Everytime when i try to copy an expression or script, i paste with "empty".
Then i had to go back to the expression again, i will do a few copy action, or i simply hold the ctrl+c for few sec, and paste again, to have the thing pasted.
i saw similar article about this somewhere, but i couldnt find it anymore.
so if someone saw similar post, please share.
