Tom:
Thanks for the feedback. A few more questions:
1. Did you have any problems with other programs by raising the MaxLocks to 500,000? How large of a ST_Data.mdb file can you now create before you get the error message?
2. I never thought of exporting to Excel, and storing it there. Exactly what gets exported, and how does the exported file size compare to the size of the ST_Data file? Do any graphics get exported, or just the data?
3. I now run all of my tests in "Quick Test" mode, but I still have the errors. The Metastock technician told me that the size of the data file was the same; only the report file was smaller with "Quick Test". Have you confirmed that there is a real size difference in ST_Data?
