Hi All,

I'm experiencing a weird problem when using vmtk - development version. I 
started using it last week and I've never had the same problem before (while 
using the binary package 0.9 for mac), but I am not sure where the problem 
comes from. 

Basically vmtk scripts work fine generally, but sometimes when I run a command, 
nothing happens - no errors, no usual output. It just seems that the command 
has been disregarded. And if I run the exact same command again immediately 
after, it generally works fine. I paste here below an example, where the 2 
commands have been run few seconds apart without changing anything else in 
between. 

Has any of you had a similar program or an idea on how to solve it? It happens 
also if I run a script containing several chained commands and when one fails, 
the whole script does...

FYI, I'm using vmtk on Mac OS X 10.6.8.

Thanks!

Lucia
