You apparently did not read my posts on the other section of this forum: New Insync version: 3.0.23.
I specifically describe the problem as missing context menus, and kyle states that context menu functionality is not yet implemented in 3.0.23. I then posted a screen shot of insync 3.0.23.40579 that says the thunar integration has been implemented. I then point out that these kind of problems need a better explanation
I originally downloaded and installed insync 3.0.19.40421. Upgrades have occurred since then.
