Since using the new version I have experienced a couple of problems I wasn't having before.
1. API connection going down repeatedly over the weekend. I note tdadba was seeing the program shut itself down - which I'm pretty sure would just have been the API connection. If you are reading this tdadba, has going back to the previous version solved the problem? I will probably do the same for now, although it could just be a coincidence; i.e. perhaps Betfair had persistent API problems just after version 7.1.0.6 came on stream.
2. My current bets refresh time has started increasing dramatically as my number of matched bets on a market increases; from about 0.5 sec to 3 secs. Again, I guess it could just be an API problem, but I'm thinking that it may be more than a coincidence that this problem arose only when I used the new version.
Anyway, I thought I would report in to back up tdadba's experience in the hope that it might help identify and solve the problem.
