I'm running 0.9.10 in Arch and Fedora. I experience this problem in both distros.
If I click on a .txt file or .html file, a dialog box appears stating "This file document.txt is executable. Do you want to execute it?" The options are Execute, Cancel and Execute in Terminal. The filesystem is NTFS, so it's impossible for me to remove the executable permissions.
I would like PCManFM to launch Leafpad for .txt files and Firefox for .html files, as I have set it to do by right-clicking and choosing "Open with...". This works correctly in Thunar.
Is it possible to resolve this? I notice that Nautilus now has an option in its preferences to specify whether executable files are executed or simply opened. This would remove the need to me to right-click on relevant files and choosing the program to open the file with. Or if there's a change I could make to a config file, I'd be more than happy to do that. Thanks.
