The problem that im expierencing is i cant edit the text inside the jvm argument. Also, all the other posts I could find were suffering from a razor mouse (or a cortex??) but i have a logitech mouse, so i dont think thats the problem. I want to change my xmx to 4g ish. Thanks!
Awesome! Apparently, I can edit the text via copy/pasting/cutting with the right-click dropdown (keyboard commands didn't work), So what i did was I changed the text, then pasted it in and it worked.
