ID 405794 - Modo GUI Mode: Slave Mode takes a Modo license

Problem summary
Running Modo in Slave mode via a GUI version uses a License up.

Customer reported version
Modo 13.1

Customer reported platform
Windows

Steps to reproduce

1. Point your machine to a RLM server with a Modo license on it

2. Launch the main Modo executable in slave mode.  Either
- Launch Modo and click on Render > Enter Slave Mode from the menu
- Launch Modo from a command prompt or terminal with -slave  mode e.g. C:\Program Files\Foundry\Modo\12.2v2>modo.exe -slave

3. Check your license usage on the server, you will still have  modo_i license checked out

Expected behaviour
Slave mode should not use a license at all

Actual behaviour
Slave Mode is using up an interactive license.

Workaround
Using a Command Prompt/Terminal, running Modo via the modo_CL.exe and the -slave option it runs Modo in Headless Slave mode and this doesn't use up a license. The command is :

Modo_CL.exe -slave

Or

Modo_CL.exe \slave
