TCMD Screen Buffer Not Working Correctly in Build 19

A new problem has appeared with build 19. When TCMD launches, the initial TCC tab cannot be scrolled back to see the output that was generated during the startup process. In fact, after generating addition output, the tab still cannot be scrolled back. It's as if the screen buffer has no more lines than the rows of the TCMD screen. But I checked, and the buffer is set to the default 5000 rows.

Is anyone else seeing this?
