[slime-devel] Hide REPL

Hi, I am using Slime/Emacs on Windows. I have a dual monitor setup. So I create a new frame, move that to the second monitor, and set that to the Slime REPL buffer. Now in my main monitor, I have the code visible. When I run a function in the main window, the window is split in half with code and REPL showing. I want to stop this behavior of automatically splitting the window. The REPL on the other frame updates, so that's not a problem. So when I run a function (C-M-x), I don't want the window to split. Can anyone please help me with this? Thanks
