I am operating TMG 7.04 in Windows 7 64 bit. Although I have had TMG for years, I've just began to use it on a regular basis in the past 9 months (since getting my new computer with Windows 7). When I pull up the Master Source List, I am never able to view the first column in the list, which I believe is supposed to contain the source numbers. Is there something I can do to correct this? Sometimes, especially when trying to convert my imbedded sources (from a previous program) to regular sources, that I want to just go to the source, rather than have to do a search of what I THINK might be in either the abbreviation or title.
