- Subject: insight combobox error (wont go away) no such variable grabstatus
With my current glibc/X11 versions, I get a combo-box
problem with insight - the combobox wont close, reports
a stack trace, saying no such variable as "grabstatus".
The problem get better with this line that sets the
variable if it hasnt been set. You would probably go
back to the root-cause which might be the foreach
never lappend-ing anything in the first place.
I dont know why this happens now, when it never used to,
but it does.
