The update window is a modal dialog. If we were to keep this open, there’s no way to use Visual Studio without closing it.
We will need to add another way to take a look at recent changed made by others by either caching the updated files list, or the before/after revision and showing the log messages between the two.

Note:
1) that update output is always logged to the Subversion page of the output window.

2) All pending conflicts (even to files not referenced in the repository) are always shown in the pending changes window.
