In Thunar, the context menu appears normally on pressing the right mouse button but it also disappears as soon as I release the right mouse button. I've already had the same issue but I wonder how it's been solved. It reappeared since Xfce >=4.7. The problem happens regardless of "Double/Single click for focus" setting I use Thunar version 1.2.0. Platform Gentoo Linux.
Here's a workaround while waiting for a fix, inspired by bug reports #3549 and #3550 (on how Thunar uses gtk-menu-popup-delay variable to determine if we want to drag a file or open a context menu). I commented out the two entries in .gtkrc-2.0 I had added to speed up menus: #gtk-menu-popup-delay=30 #gtk-menu-popdown-delay=30

I'm now using Thunar 1.2.3 and I think the problem disappeared since 1.2.1. Not quite sure though. It's been a while I haven't experienced this anyway. It works for me on my two Gentoo machines with all of my user profiles now.
Arch Linux 64bit, up-to-date system, Thunar 1.2.3-3 from the official Arch repo. Just started using Xfce, so I don't know about earlier versions, but this one has the right click menu problem and workaround I posted above helps.
