Whenever I try to use the Start Menu on the DisplayFusion taskbar, it appears briefly (1 second or less) and then disappears before I can click on anything. Everything else on the taksbar works, but only the start menu has been rendered useless. This is happening on all PCs that have the product installed, and all are upgraded to the most current version. This has been going on for quite a while, and I was hoping recent upgrades would correct it, but it's still happening.

Here's the debug report.
