Sorry to ask but I think it's better to ask a silly question than to continue an ignorant.
PT4 brought changes to the caching; and, along with other users, I might experiencing problems with that (playing at 888).
But... what is the caching for? Is it only for HUDs or for the graphs/stats as well?
I ask as well because someone just asked me to analyse a database. What I would do in PT3 was just to import the hands to a new database and not cache it (since it saves a lot of import time). I'd look at the stats and graphs and that was it. Now with PT4 I felt discouraged as I don't really look forward to spend 12 more hours importing a database just so I can analyse it...
