Multi on UltraVNC SC

[vncoffe]

Hi all.
I've been using UltraVNC and UltraVNC SC for years to support my clients. It was great until recently, when I updated my old UltraVNC SC version.
After the update, I discovered the following incompatibility between UltraVNC Server Service, UltraVNC SC and my use case.

Use case:
- UltraVNC SC for quick remote helpdesk.
- UltraVNC Server Service for maintenance jobs or remote helpdesk requiring reboots.

Problem:
In many cases, the user starts connecting with UltraVNC SC and I, remotely, install UltraVNC Server Service through that UltraVNC SC session.
In other cases, after finishing a service mode session, I start an UltraVNC SC session to uninstall the service and "clean the house" (remove any remote access setup).
In both cases, I run, for short periods UltraVNC Server Service and UltraVNC SC simultaneously.
This worked very well with the multi parameter, but I see that UltraVNC SC no longer supports this parameter so, when I try this, y loose connection.

Has anyone else encountered this issue or has a solution or workaround?
