I am working with a Word (2003 version) document and I have two instances in my end notes where there is an extra space between entries. I have tried clicking on the formating icon on the tool bar (the one that looks like a reversed "P"), but I can't get rid of the space either by back-spacing or by delete. I am still in the track changes mode.
Sounds like the paragraph spacing is too large:
If this is the case, simply select the offending text, right click and select Paragraph... The window you see above will appear. Reduce the Before or After spacing to the desired amount (probably 0 pt)
