ok, got it working. Thanks for everyone's help. Here is what I have
done,
The launcher has a datagrid AppPicker contains the links to the files
available to launch.
on mousedoubleup
set the itemdel to tab
put the dgHilitedLines of grp "AppPicker" into tLine
put the dgDataOfLine[tLine] of grp "AppPicker" into tData
put tData["theLink"] & "#" & the milliseconds into tURL -- this will
force a reload is the same link is used
if laststack is among the lines of the openstacks then -- if there
is a stack in memory, delete it
delete stack laststack
put empty into laststack
end if
put the openstacks into stacklist -- remember what was open before
the call
go URL tURL
get the openstacks -- figure out what is new, this must be the name
of the new stack
repeat for each line x in it
if x is not among the lines of stacklist then
put x into laststack
exit repeat
end if
end repeat
end mousedoubleup

I am building a launcher app the loads stacks from DropBox.
I am using
go URL tURL where the tURL is the stack to load using the correct
DropBox format.
This works great for the first load. However, if I update the stack
in DropBox and try to reload tURL, it does not purge the existing
stack and load the new one.
Okay so when you do 'go url tURL' what is actually happening is you
are doing:
go (<expr>)
If <expr> evaluates to binary data which looks like a stackfile (after
the engine's tried viewing it as a name of stack, and failed) it will
try and load that binary data into memory as a stackfile. If there is
already a stackfile in memory with that name, then the normal engine
processes will kick-in and (most likely, as the stack doesn't have a
filename) cause the existing stack which is in memory to be preserved,
and the new one ditched.
Now, a stack loaded with the above form will not have a filename, so
'revert' won't work. Instead, you'll probably need to do:
delete stack <nameofstackwhichwasgourld>
go url ...
Hope this helps!
Mark.
