Will not flash to a Pro Micro

Describe the Bug

I have a Pro Micro that I have been using for a while now. The new version (0.3.2) of QMK Toolbox is not flashing changes. Below is the "console output" from an attempt to flash. During the "flashing" the built-in LEDs do not flash.

Note that it does not matter if I do or do not use Auto-Flash. To verify this is an actual issue I have tested the same hex file using version 0.3.1 and it will flash correctly. During this test the built-in LEDs do flash.
