Comment 23 for bug 147751

Old versions of AllTray won't work with Compiz due to the way that it works (and also even if it were to significantly change how it works, old AllTray hard-codes its behavior for Compiz, so it still won't change). The problem is that classic AllTray does not pass along XDnD events to the underlying application after it has reparented its window.

The newer versions of AllTray are not affected by this bug because it never reparents windows. However, there are a couple of bugs to try to work out; for example, it doesn't work 100% correctly with applications that are built on top of the Mozilla code base for some reason that I have yet to determine (and one very popular use-case for AllTray is to dock Thunderbird, for example). When I finally figure out the why and work around it, I'll be able to release 0.7.6dev, which will likely be (if no bugs are found) subsequently released as 0.8.0-rc1 and eventually 0.8.0.
