After a period of some minutes of inactivity in my poderosa window, all open session tabs are gone. The poderosa window is open, but no tabs. This has happened several times.
poderosa Version : 4.3.8b CLR : 2.0.50727.5456 on windows 7 connected to IBM AIX using SSH (2)
I dropped back to using Version : 4.3.5b CLR : 2.0.50727.5456 and still experience the problem.
So I conclude that the problem is caused by some thing in the data profile being saved by poderosa
