MT4.01: I'm writing an entry named "welcome"; it auto-saves at some point; when I save and publish it and am returned to the edit entry page, suddenly I'm editing an entry with basename 'welcome_1'. I don't notice the basename, but I do notice that when I edit the entry, I'm not seeing the changes reflected on my page. Then I scroll down and realize that the entry appears twice, and my changes are being made, but to the entry with basename 'welcome_1', which for some reason appears as a previous entry to the one with basename 'welcome', even though its basename suggests that it would have been a later entry.

I've occasionally had a similar issue with duplicate unpublished entries showing up in the entry manager. It doesn't happen every time, but I'm pretty sure it has something to do with auto-save. My best guess is that it's auto-saving at the same time that I click the save button, and the latter doesn't override the former. Has this happened to anyone else? I definitely want entries to auto-save, but this is kind of an annoying, if only occasional, side effect.

For some reason when I used my grandfather's computer over the summer, a long entry that took a while to write might yield 20 or more copies of itself in various stages of completion, but that was in MT3.something using the auto-save plugin, before I upgraded. I don't know if that would still happen or not; he lives far away and I haven't had a chance to visit again.

Just for the sake of checking, you don't still have that old auto-save plugin installed, right? There's a decent chance it wouldn't work with MT4 anyway, but no sense in leaving it lying around.

It sounds like this is happening consistently. If so, try disabling auto-save by setting AutoSaveFrequency to a value of "0" (no quotes) in your config file. This will at least let you test your theory. Have to admit I don't think I've seen anyone report this for 4.01, so if that confirms it, I'd submit a bug.

I just double checked to make sure I'd gotten rid of the plugin, and I did. I'll try disabling it and see what happens, but admittedly I'd rather deal with the duplicate entry issue than risk losing something because auto-save is turned off. I'll have to think about it.
