QM wants to connect to TWS

Hi,
I am using MC8 beta3 64.
Situation:
Portfolio Backtester is running with freequotes.
Connected to TWS and just closed the last chart on MC that was connected to IB.
Waited a while until QM stopped showing updated messages on the log
I close MC.
Now I close TWS and this lines are coming up and does not stop.

“Connecting to TWS… host= 127.0.0.1, hostIP…….
Connection to TWS failure. Is the Interactive Brokers TWS software running and is it enable for socket client? Is firewall disabled? Res=0”

So I opened TWS again… QM stopped showing the lines.
I opened MC with an empty workspace… Waited a while and closed MC. Meanwhile Portfolio Backtester was finished. I closed TWS.
Again QM constantly showed those 2 lines.
Launch Trader Workstation is not set.

How can I stop those 2 lines filling up my logs?

EDIT: I restarted the computer and started TWS, QM and MC. Opened "BAC" and closed it again. Closed MC and after a while TWS. QM keeps on showing those 2 lines.

EDIT2:
On beta 2 this only happened when I didnt let MC disconnect from a stock. On this issue I did let him disconnect from the stocks.

Hello Siscop,

What chart resolution are you using?
Do you have "Collect data without plotting" enabled for IB instruments in QuoteManager?
Is “Utilization of cache for real-time price data” enabled in Quote Manager->Tools->Data sources->IB-> Settings?
