<span class="gmail_quote"></span>Hi<br>
<br>
We've been working on 'friendifying' OpenEV for use with the Protected
Area Archive (see <a href="http://asterweb.jpl.nasa.gov/paa" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://asterweb.jpl.nasa.gov/paa</a>, although note that
the screenshots on the site are from an old MapObjects Lite version of
the tool). <br>
<br>
I realize that this may already be outdated given Marios superb work on
the GTK2 port (fingernails chewed off in anticipation of a release!),
but wanted feedback from this list on some of the changes we had
introduced. <br>
<br>
A quick summary of changes follows. Could some of these changes be
incorporated into the formal releases of the FW_Tools version of OpenEV?<br>
<br>
Best<br>

PS. Can send code (either seperate .py files and icon .xpms or a bundled installer to anyone interested).<br>
