Has anyone seen this problem before with 11.1 ?I don't run anything on local hyper-v anymore, but I do run a ot of stuff in Azure, and we havent seen anything like this. I track STABLE for things though, updating after reading the commits and testing locally for a week or so, so the version I am running currently is r320175, which was part of 11.1-BETA2. I am going to upgrade to a more recent STABLE sometime this weke or next though, will do that on a test amchine and let you now how it goes. I seem to recall that there were some large changes to the hn code in August to add virtual function support. When does 11.1-p1 date from ? -pete.
