maemo.org - Talk - Hildon question

Hello, I am fairly familiar with creating 'desktop' entries of this nature:-

Code:

[Desktop Entry]

Encoding=UTF-8

Version=0.1

Type=Application

Terminal=false

Name=Cell on

Exec=my_command

Icon+my_icon

and placing them in:-

Code:

/usr/share/applications/hildon

If have no problems getting this kind of thing to work on my N900's.
The issue I have is that whenever I 'click' on 'my_icon' the stsm always brings up a black 'terminal' when 'my_command' is executed.
The terminal is only there for a second or so. I find it a little annoying.
Is there anyone out there that knows a way to stop this, or even another way altogether of running commands 'under the cover' by
tapping an icon?
Regards
Richard.
