Quit Command corrupts standalone (stack called by standalone splash)

[Phil Davis]

Roland,

I believe Tom is exactly right. I would restructure your two closing 
handlers like this:


local sMyFilename

on closeStack
     put the filename of me into sMyFilename
     saveMe
     send "quitMe" in 1 second
end closeStack


command saveMe
    lock cursor /* Tested with and without locking and showing cursor */
    set the cursor to watch
    save this stack /* auto save, takes a long time, between 10-30 secs */
end saveMe


command quitMe
    if there is a file sMyFilename then
       unlock cursor
       lock messages
       quit
    else
       send "quitMe" to me in 0.5 seconds -- or in your preferred time
    end if
end quitMe


The above was not tested but it should solve the problem.
