Details:

Some commands/actions cause the Command Window to output a newline every 30
seconds or so. Even when in the middle of entering a command.

Once it starts, there does not seem to be any way to stop it.

Things which seem to cause it to happen:
* Expand a directory (the '+' icon) in the File Browser panel.
* Select a recent directory from the File Browser current working directory
choice/drop-down/combo-box control
* Double-click a directory in the File Browser panel.

Things which don't seem to cause it to happen:
* Scroll the list of files/directories in the File Browser panel.
* Show the drop-down list of recent directories (without selecting one)
* Select (single-click) a directory in the File Browser panel.

Additionally, some commands seem to trigger the problem fairly reliably -- but
not universally:
* 'cd Someplace' (no quotes)
* 'cd ".."'
Others do not:
* 'cd "Someplace"' (with quotes)

Clearing the command window does NOT stop the periodic newlines.

Unchecking the preference "Synchronize Octave Working Directory with file
browser" does not stop the periodic newlines, nor does it prevent them from
happening in the first place.

Configuration:

Windows10 (yes, I realize this is still experimental)

GNU Octave, version 4.2.1
Octave was configured for "x86_64-w64-mingw32".

Installed from "octave-4.2.1-w64-installer.exe"

Invoked from "Octave (GUI)" choice on Start menu
