It may help you track down exactly which part of the GL setup

I know almost nothing about OpenGL but using your
method(sorta):
void reportGLErrors() {
GLenum errCode;
const GLubyte *errString;
if ((errCode = glGetError()) != GL_NO_ERROR)
{
writeln("OPEN GL ERROR: ", errCode);
}
}
I get error code 1282 repeatedly.
From a google search someone says:
"First, glGetError() will return 1282 - invalid operation if
the GL
context is not current (or not yet created). So, create your
context
first, then call glGetError. And, verify that any parent class
or member
class does not call GL functions in their constructors or
prior to
context being created."
Can someone with more OpenGL knowledge clarify what this means?
1. Program starts
2. Window gets created
3. Context gets created
4. Context is activated
5. Profit???
Basically before the context is created and activated you
cannot call any OpenGL functions. If you do, they will error
out.
The bit about constructors ext. don't worry about it. Its just
about e.g. where the calls to OpenGL can exist.
Yes, my bad sorry, but whatever works. The point is dive in and
start printfing about in Window.d, checking error codes to try
and figure out where things become stuffed up.
