On one of two nearly identical WXP SP2 machines E@H was found to be running work despite having received warnings that BOINC 4.19 was needed. On the other machine, no work was furnished over the last few days, as expected from the messages on that machine.
Looks like a bug!
Both machines now at 4.19 level.

E@H continues running on BOINC 4.18. Bug?

Sorry, missed it in the first writeup - as implied, both machines were on the 4.18 level at the time the difference was observed.
