Since Version 12 the burning of CPU for no obvious reason when logging on seems to have vanished.
Could it be they got cold feet from getting caught with the hand in the cookie jar, or maybe they just finally looked over the code from that 9th grade intern they let lose on their cash-cow. Could it be an admission of shame and guilt that the release notes AFAIK didn't mention fixing something that important? Inquiring minds want to know.
Anyway, problem currently gone for me. Should a few more be able to verify this I think we can consider the problem solved (for now - give it a few weeks to return
).
