TightVNC 2.7.7

# Server for Windows:
- Fixed a bug with multi-monitor configurations running on Windows 8. The main display can be safely set to any monitor in a row or column.
- On Windows 8, data is no longer corrupted when the screen resolution is not divided by four (native resolution for some laptops).
- No more issues on the Server side when a zero compression level is set in the Viewer settings (Options > Set custom compression level > level: 0).
- Fixed incompatibility with older versions of TightVNC Viewer (1.3.10).

# Viewer for Windows:
- Fixed a keyboard bug: it stopped working after a file transfer window is opened.
