• hehemouse Invoke freezes and BeginInvoke queues up too many messages.

A second thread runs a very fast running loop that obtains data and controls a piece of hardware (or simulates such). When the second thread gets an update, we have it use Invoke to update the GUI.

But it doesn’t print from my C# program, it’s like it doesn’t recognise the data being sent to it.
