I noticed on the update to 6.1 that although I get the hover text on problems (when minimized) it will show me the number of errors and warnings, but when I expand the window - it's blank.
Sometimes the window populates eventually if I restore it. Sometimes it doesn't. But temporarily expanded like this as a minimized window it NEVER lists the problems. Usually I have to restore and recompile before this list will populate (very annoying).
Zoomed in you can see i have 4 warnings, but they're not showing up in the list.
