After Effects GUI very small when run from afterfx.com

I generate extensive debugging console output from my After Effects SDK plug-in effect.  Running afterfx.com from the Windows cmd console opens the GUI while writing out my debugging messages.  This all works fine on my one PC that attaches to an HD display.  However my other PC has a 4k monitor attached and running afterfx.com from the console causes the After Effects GUI font to be so small as to be unreadable (I'm assuming a possibly non-existent connection there between display size and GUI -- the font should still not be so tiny).  If I run afterfx.exe from that same command line on the 4k machine the GUI is fine, but every line of console output creates a new console window momentarily rather than writing to that same open console.

Is there a way to adjust the size of the After Effects GUI display when run from afterfx.com so that it remains readable on the 4k monitor?  Or failing that, is there another way I can capture or redirect this output stream, other than writing it to a file?  If I was on Unix, I'd probably write it to a file and spawn tail -f on it from another shell.  I don't know how to do that in Windows.  Any suggestions would be deeply appreciated.
