no problem.. it would be pretty important to know that in order to compile

from within xterm just do this :

/media/mmc1/source/winforms $ ls -l
-rw-r--r-- 1 user root 948 Mar 25 15:39 hello.cs
-rw-r--r-- 1 user root 4096 Mar 25 15:39 hello.exe
/media/mmc1/source/winforms $

so ls -l (read LS -L except lowercase) will print directory saying who owns it and what permissions are... i currently run off mmc (fat) so it just says user owns, anyone can read, and user can write.

So do an ls -l then using stylus highlight those lines and in menu do edit/copy... then paste into a reply to this message from device (if you can or just type here what the roundedrects.cs file permissions and owner is)
