Hi, I run into this error once in a while. It happens when application is doing nothing but showing its form, but no actions or anything is performed. I run application and IDE at the same time (by clicking application icon, not under debugger).
Well that's no way to debug a program. Run your program in the debugger.
So, once in a very large while, it will display this message, exception handler is constomized, so I get more info.
The only additional information you're providing seem to be the "origin" and the "TID"; what do those mean? Where does that information come from? How do they help you find the source of the problem?
What is this, and how do I track this thing down??
That error message occurs when your program calls RaiseLastOSError (or RaiseLastWin32Error) even though GetLastError returns NoError.

A call to an OS function failed.
(TID:6800) - 0x00467E00 - 0x00000000
Type: "EOSError" Origin: "TApplication"
OK. So what API function did you call at address 00467E00? This is where a debugger would help.
