My observations over the last couple dozen minutes: Unchecking the option to install uTorrent during the setup disables the Additional Settings panel on the next step, even though those options can be enabled later when you run uTorrent without installing it. The disabled menu buttons seem to have a 3D border that detracts from the asthetic appeal. Maybe remove that border? Right clicking on the Remove button while its disabled shows the context menu and makes the Remove button enable itself for a small duration. The uTorrent help file still shows uTorrent as being v1.8.0. uTorrent 1.8.3 build 15619 shows 15772 in the help file. The help icon in the Preferences form seems to be resized poorly. White pixels around the edge are visible. The dialog box thats visible when you hit Help -> Show Statistics has a lot of empty space on the right (in Windows 7 at least). Similarly, the Preferences form could be made a bit shorter as the longest panel leaves some space down the bottom: http://i30.tinypic.com/2ymdpfm.png The font for the disabled Scheduler Settings under Scheduler in the Preferences form differs from the enabled font: http://i28.tinypic.com/2v8fn5y.png Similarly, the font for the Transfer Cap panel under Transfer in the Preferences does the same, as well as the two labels under UI Extras when the "Override automatic [...]" checkbox is unchecked. In the RSS Downloader form, the left side of the ListView or ListBox item on the Favorites tab doesn't align with the left side of the ListView item on the History tab. The Setup Guide form seems pretty bare when you first see it. Maybe consolidating the free space is a good idea. When running a speed test in the Setup Guide form (and after as well), the text for the Suggested Settings panel gets cut off and isn't disabled: http://i30.tinypic.com/21l0eox.png More Setup Guide inconsistencies: When you dont have a server selected, a dialog box comes up (that arguably shouldn't have a capital S for server) that not only changes the font for the disabled Network Test panel text, but also doesn't disable the "Automatically test your [...]" label (which happens to be too close to the Suggested Settings panel text to begin with - might be causing the previous issue): http://i27.tinypic.com/2qa4dpy.png If you uncheck Speed Test in the Setup Guide form and hit Run Test, you are unable to run another test with any combination of selected tests checked or unchecked. When disabled, the Skip Files label in the Create New Torrent dialog has a different font than when enabled. Creating a new torrent (30MB) takes a very long time (10 seconds). CPU usage was very low (~2%) and never maxed out a single physical core, even though it should have considering the HDD is not the bottleneck. When a torrent is made of a certain folder, and that folder is subsequently removed, trying to create a torrent of that folder (by just opening the Create New Torrent dialog) leaves the Skip Files label and text box disabled. Under the Seed While panel in the Torrent Properties dialog, the font for the text that is disabled when the checkbox is unchecked is different than when it is enabled. The Torrent Properties dialog shows redundant characters (the pipe symbol) in the title when multiple torrents were seleted. The Add Torrent from URL dialog box's sole label should say ".torrent file", not just ".torrent." The Logger seems to show certain entries twice: [2009-08-05 01:28:48] Loaded ipfilter.dat (0 entries) [2009-08-05 01:28:48] *** Starting Diagnostic thread *** [2009-08-05 01:28:48] IPv6 is installed [2009-08-05 01:28:48] Got Teredo Address: xxxxxxx [2009-08-05 01:48:37] Connecting ...

The default width for the columns under Advanced in the Preferences dialog could use some adjusting.
