Tree!explorer, file context menu not working? Options

[Retief]

I've got Tree!Explorer on my C860, and the menu for files doesn't seem to be working as it should. When I tap-and-hold on a file, the menu appears. If I select 'open', I get the Properties popup instead. If I select 'open with', nothing seems to happen. If I select 'send to', the submenu just has a couple greyed-out items. Any idea what I'm doing wrong?

Also, I've tried editing the treeexplorer.conf file to add to the sendto menu:
[sendto]
item0=/home/QtPalmtop/bin/zeditor
...

but that seems to have no effect on the sendto menu, even after restarting Tree!Explorer?!?!

I've posted a note on the author's site, but I thought I'd seek to collected wisdom of y'all as well.
