Hi again:

I put your code into those routines which are called in the vicinity 
of the crash. No error during the operation from compiled routines.
It crashes again IDL coming up with Dr.Watson. The exception is an 
access violation 0xc0000005 at address 0x02854f14. The problem 
is that you cant step through a program loaded from sav file. Since 
the error doesnot occur during the operation from freshly compiled
I am trapped ..... Probably its better to report the error to RSI
or to wait for IDL5.4.

Best Theo
