Hi all, I don't know why but the command window that hosts the emulator on my laptop has suddenly grown to such a size that I can't close it without right clicking on the icon and selecting close, until yesterday the window had the normal minimize,maximise and close buttons in the top right hand corner like all windows shells do, I've tried uninstalling Android Studio but the problem persists, the only thing I know I've done is download some more SDK packages but I didn't change anything else knowingly - any ideas guys ? This is a nightmare as I'm writing an app for a client and at present I'm forced into using AIDE on a tablet so I can continue working.
