MiniGW; Problem with errors

[m3athead]

When I try to compile my C++ project, I can see the errors in the actual code but no separate window pops up with each individual error like it used to. I noticed there is a "Build ended with errors, click to view" button in the bottom right but it is unresponsive. All that has changed since I've last compiled something was switching from two monitors to one. Is there a way to enable this window to pop back up?

Thanks
