IB - latest TWS - no paper trading TWS and real TWS open at the same time

[Maverick2608]

With the latest TWS update, I cannot have a paper trading TWS and a real TWS open simultaneously as I could before. Has anyone experienced the same change or found a solution?

Thank you.

I found the solution, which is to choose:run TWS using Java WebStart

Is this a new feature or a new bug of TWS? You never really know with IB......
