When running under Xfce as 'root' or a regular user, and you right mouse click on the desktop, it will bring up a menu with the 'Open Terminal Here' conspicuously absent. Earlier versions did not suffer from this. The 'Open Terminal Here' option *is* available in the Thunar instances, just not on the Desktop. Further the 'Open Terminal Here' is set as a custom action, and appears to be configured correctly. This is inconsistent with menu options for Thunar versions prior to 1.8.2 Happens under Slackware-current (both 64-bit and 32-Bit) and under Arch Doesn't matter if root or regular user
Sorry, this is a known compartibility problem. Thunar Plugin API has changed, and xfdesktop 4.12 still uses the old API. As far as I know it is already fixed for the development release of xfdesktop ( 4.13.2 )
Yes, this is an unfortunate outcome of releasing Thunar ahead of other components.
