multiple tabs in one sCRT window

[wbcattell]

I have 3 machines running SecureCRT 7.0.3. On the system A I can open a session then later open another session and it opens in the same window.

On systems B & C I open a session and a window opens. If I need to open a different session it will open in a different window, not the original.

I've been looking through the global and session configs trying to figure where to make subsequent sessions in the first window. A minor in convenience until I want to paste into all the sessions - then it's a problem.

Where do I tell subsequent sessions to open in the same window?

TIA,

Bill
