Amith, If you're using Windows 10, there is a setting to control the scaling for your monitor (see the attached screenshot). Going beyond 100% scaling will make all text and icons bigger. If you just want to change the font size of the command line and nothing else, I've attached a Python script just for that. The font size is controlled by the "new_size" variable towards the top of the file. If you want to change the log font size, I've noticed you can hold down control and scroll with your mouse while hovering over the log to change the scaling.

It may have something to do with Windows not allowing stdin/stdout for GUI apps. www.cgl.ucsf.edu not sure if things have changed after that. thanks , amith
