I just got a popup that ESignal's new build 11.5.2964 is available (says new 2/11). This is just a few days after another new update on 2/7 (which I got a popup about but I held off). Sheesh. I have been keeping up to date with all of the new releases, but I always always wait at least a few days after the notification to give the loved ones at ESignal a chance to fix their booboos before they become my booboos. Just a thought. And, yes, it was a total headache to upgrade from 10.6 to 11.5 and I wished I had never used ESignal ... but I've used it for so long that it was more of a pain to switch to something else. Everything else I tried (many others) did not do what I was used to, although the price, of course, was better. I wasted a lot of time looking at other stuff and ended up continuing with ESignal. I think the 11.5 works better/faster than the 10.6 but it might be my setup that is better now. Only once has it threatened to crash on me, said I had too many pages open. But when I shut it down and started over, all was fine, and no problems since then. Just be prepared to spend quite a bit of time if you're updating from 10.6. Many changes. I'm still keeping things as simple as possible because there are just too many changes and I haven't had time to spend learning all of it. Hope this helps.
