Thanks to all I am fine now using :
Button26, "Save session button"="Save window setup, , , "Save session button", "YOUR_BUTTON_ICON" & Delay, 500 & Focus next widget & Uncheck item & Focus previous widget & Clear & Insert, "Session" + Show popup menu, "Internal Session list""
.......................and fill in the dialogue box " autosave "
I need to do this as everytime I restart from a crashof verion 11.50. Session came up is out of control and it may appear session from very old days instead of the recent one.
Thank you very much once again.
