Keep getting the 'Cross-thread operation not valid' when trying to show the menustrip of a notifyicon

This is not a regular 'Corss-Thread opeartion' BS, so don't post the obvious solutions please.

This is something that's been driving me crazy for days now.

I have a NotifyIcon, with a binded ContextMenuStrip. Everything works as it should, but sometimes (and I can't recall the exact steps to reproduce this) I get the cross-thread exception. All my access to the ContextMenuStrip/NotifyIcon is padded with the Invoke cr*p, but still - when the user right-clicks on the notify icon - the exception is raised.

This is the full data from the exception:

Message: Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on.

As Doggett pointed - my ContextMenuStrip was initialized under the OnLoad, instead of the ctor... once I moved it in the ctor - problem disappeared.
