I'm seeing an inconsistency in the behavior of a widget program which is being
restored from a save file...depending upon how it is restored. The two ways I am
restoring the same program are:
1) % idl -rt=myprogram.sav
2) IDL> RESTORE, file='myprogram.sav'
The demo program below, which I've named popup.pro, creates two simple
non-blocking windows that are dismissed by pressing the "Done" pushbutton.
I create the 'sav' file by:
IDL> .compile popup
IDL> resolve_all
IDL> save, /routine, file='popup.sav'
Now, if I issue
IDL> RESTORE, file='popup.sav'
and type 'main', I get two working windows which can be dismissed in either
order (what I would expect.) However, if I use idl -rt=popup.sav at the UNIX
prompt, the first window blocks, and I don't see the second window until I
dismiss the first.
I looked through the IDL Runtime Guide, but didn't see anything pertaining to
this kind of issue. Has anybody else encountered this kind of behavior? Or
am I missing something? I'm running IDL Version 5.2 (sunos sparc).
