Solar PuTTY can only create 10 sessions at most?

Tried many times and Solar PuTTY would say "Fatal error!" (see attached screenshot) when creating the 11th session. Not sure if the limit is by design or not. Anyone hitting the same issue?

  • Your screenshot appears to not be visible - at least not to me it isn't.

    However, and just a thought: If this is always from/on the same box then are you running low/out of memory? And what about use of standalone putty instead, does that also fail on the 11th session?
