YVD currently requires a minimum screen resolution of 1024x768, and is not resizeable. This has been a problem for users with Netbooks, as a lot of them have a maximum resolution of 1024x600, making it impossible to click the Chat and Duel buttons. We are currently working on a new version of YVD that will eliminate this issue, but until then, we have some workarounds that seem to work for most users, but for some they do not (in which case you'll have to wait for the next version or use a different computer)
First of all, check to make sure your DPI settings are set to 96, as described in Section 6.9.
Next, try changing your resolution to 1024x768 anyway, as some netbooks will let you do so and will just scroll when you move your mouse in that direction. These links below can walk you through that.
For Windows XP
For Windows Vista
For Windows 7
If you cannot change your resolution higher by default, you can try to force your screen to allow unsupported resolutions, which can either set your screen to scroll as described above, or it will make your screen go black (but will revert in 15 seconds). Please note that this method only works on Windows XP (and possibly older versions, but that's untested). Microsoft removed this functionality in Windows Vista and Windows 7.
To force a screen resolution in Windows XP, follow these steps:
1. Right-click a blank area of your desktop and click Properties (alternatively, you can go into your Control Panel in Classic View and open up Display).
2. Select the Settings tab at the top.
3. Click the Advanced button.
4. Select the Monitor tab at the top.
5. Uncheck the box stating, "Hide modes that this monitor cannot display."
6. Click Ok.
At this point, you can now select a screen resolution of 1024x768 or higher to support YVD. If this does not work and your screen just goes black, wait about 15 seconds or so and it should revert to your old resolution.
