This has been persisting for the past couple of months. When I go to Packages > Install and try to type the name of a package I want to install in the text box ('Package archive' line), I am unable to type anything. I can't even put a cursor in the text box. Is there a fix for this? I can still install packages using install.packages() but it's kind of annoying that this just broke for no reason and hasn't been fixed. Any ideas?
