Three possible explanations for http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1292767978.1292770501.19646.gz: * some Windows equivalent of the Mac Bluetooth dialog is up on the slave, stealing focus * some intermittent thing was up stealing focus, but the reboot at the end of the run cured it and we'll never know * somehow that first test that has never failed before did fail, and managed to do so in a way that would take out all the subsequent tests that needed to regain focus Given how little the test is doing, how long it has been around, and how very many tests we have that try to open a window and time out without killing focus, I'm inclined toward one of the first two explanations instead.
From the output I would lean towards the first two options. After the reboot there is not much I can see. Let's hope that a utility like in bug 589668 could help us capture focus losses. Thanks philor.
