I've been ignoring the problem, but working on the web site the Settings: Date Range only sometimes works as advertised. For example, I'll open or clone some published model, with the Most Recent N Years option selected and set to 20 years, and it will work as such. And if I change it to 10 years, that will work, but setting it back to 20 years will not set it back to such (stays at 10) and I've never gotten ANY of the in between values to work (usually shows me 10 years). And this goes for just about all the possible Date Range settings. It seems very good at (and has a predilection for) showing a 10 year backtest. The most recent example of this for me was the simple MA Crossover model where it came set to Last 5 years, and no amount of selecting other years seemed to change (graph never changed, although minor model output changes occurred) but it seems to happen with all models. In this last case, changing it to Year Range allowed me to see 20 years of backtest, but then switching it back to Last N Years and 20 years only showed me 5 years of backtest. Confusing behavior! I am working on a mac in safari, if that should make any difference at all.
