Reid, there seems to be a problem with keeping the line numbers in sync as it is.
Pull up a Multi-Edit macro file.
Insert some blank lines somewhere. Say, 8 lines after line 250.
Go down to line 270, and type some garbage. Then compile it.
The compile error will be on line 270.
The error message will say that the error is on line 270.
But the edit point will be positioned to line 278, which used to be line 270.
This is a nuisance.
