Concerning the retaining:
I had a similar problem. From the RSI website I found the
following workaround (could not find the tech tip again):

The problem lies within the open gl hardware rendering.
A workaround is to force IDL into software rendering.
To do this:

cd (as user root) to the rsi subdirectory
(usually /usr/local/rsi/)

form there cd to:
idl_6.0/bin/bin.linux.x86/
(or on non-linux: idl_6.0/bin/bin.OS_NAME.ARCHTECTURE_NAME)

and do a
mv gl_driver.so gl_driver.so.off

after restarting IDL retaining worked again for me.

HDH,
marc
