I'm running the 32 bit version of XP Pro SP3 with all of the latest critical updates installed.
When I try and use the Start Menu launcher, I get this error: -
"StartMenu helper was injected but failed to take effect"
Browsing this forum I see mods telling other people with the same issue that it only affects the free version, yet I emailed Stardock support and they said it's a known issue with ObjectDock Plus and will be fixed in the next version - that was months ago and no updated version has been released.
As for the system tray feature, that doesn't work properly either. For example, my PC has Realtek on board sound. The system tray icon is only small, so it looks blocky and low res when used with ObjectDock. If I change the icon, when I click it to bring up the volume controls, they hang and I have to end the task via Task Manager.
If it's working OK for you that's fine, but it's not for me and others.
