external c shared libraries [message #16605]

hello IDL gurus: i have a couple questions re: calling external c
functions from IDL. platform: unix OSF/1, version: IDL 5.2

1) in doing development, debugging, etc. i notice that once the shared
library is changed (recompiled), IDL will crash and burn if i try and
access the changed shared lib. i can understand this happening, but is
there a way to prevent this?

2) my shared library function returns the correct values into IDL, but
then a few moments later, as IDL is waiting statically for user input, IDL
will just seem to spontaneously crash. why? mind you, this only occurs
with IDLDE. with the line command version IDL, i never get a crash.

thanks in advance!
