I, as many others, had this problem that after upgrading to v1.1.2 the script stop working, at least !dir, !cd commands, in the debug window I see this:
Error: Overflow (code: -2146828282)
File: FileServer.js. Line: 340
after little examination and debuging, I found what caused the problem in my case: the configuration "seconds before automatic logout
". Basicaly that number can not be bigger then 86400
So, if have problem with the script, try change that number.
