Notes:
1. For best results, uninstall the current driver on your system, restart, temporarily disable antivirus software & Vista's Windows Defender and install driver version 6.05-7. After completing the installation, re-enable your antivirus software & Vista's Windows Defender.
2. For concurrent use with a consumer pen tablet, install this driver as well as driver version 5.05 or later. These two drivers can now be added or removed independently of each other.
3. USB tablet required for Windows Vista (64 bit) and XP x64.
4. Serial tablets require connection through an on-board serial port. Connecting serial tablets through a USB-to-serial adapter leads to unpredictable results, and the Wacom driver does not support tablets that are connected through such adapters.

WacomTablet_6.3.19-6.dmg was release on Dec 23rd... I installed it... It removed ALL functionality of modifier keys (Command, Option, Control) in all apps which weren't 'Wacom-aware'. A BLATANTLY OBVIOUS MAJOR BUG... yet the driver was still released. This seems like standard practice for the folks at Wacom now... release something... wait for users to report bugs... make 4 more versions, all introducing NEW bugs over the next few months...... Eventually landing on a driver that seems fairly stable... so it remains in use for 2-3 years. Then they restart the cycle.... Horrible development and unlike Wacom in the 90s or 2000s. I suppose OSX may have made the difference, when they started REQUIRING reboots upon driver update (didn't need that before). I'm still using Driver 6.3.15-3 because thus far, it's the last release WITHOUT major bugs. I'll try this new 6.3.19-6 release, but I have little expectations that it will actually be bug-free -- more a matter of if I can live with the bugs it (probably) has. I don't necessarily blame Wacom for having difficulty squashing bugs... but it is their fault they releasing bug-ridden drivers without bothering to test them at all.
