I ended up clipping, parsing, and pasting before leaving each adventure to help preserve data integrity. Once I got into a rhythm it took about 5-10 seconds per update. My crashes usually occur when I select "Return To Map", but I lost a few drops due to lockups on the Collect Loot page after the treasure dropped. I also lost some because I forgot to turn 'verbose' back on after a crash. I sometimes ran into a problem in chrome where the data could be highlighted, but could not be copied to the clipboard. Ctrl-c still worked in other programs when this happened. My old 32-bit vista laptop is not a prime test-bed for this, and I expect (hope?) newer and more robust machines will perform better. I haven't tried a lengthy run in FF, so I'll probably give that a shot. I look forward to seeing the excel spreadsheet in action!
