Occationally when R# indicates there are errors in the file, the marker bar doesn't show any red markers. I have attached an example where it indicates there's an error but I am unable to see any red markers. I am using the latest build 4.5.1238.
May I suggest an enhancment where clicking on the status indicator makes the cursor go to the line with the error and with the clicks, it cycles through the lines with the errors?
Sometimes it becomes a game of Where's Waldo to find the red marker in the sea of warning markers.
