Comment 30 for bug 403421

For me, this problem can be resolved by using the Wacom Table Preference File Utility (on Windows 7 Home Premium 64-bit) by removing prior settings for the Wacom Tablet. The problem only occurs whenever I make custom settings (like binding a key to a button on my tablet), although it doesn't occur immediately after changing settings.

The problem does not affect all pen-controlled applications, but Inkscape -is- always among the affected applications. This seems to suggest that Inkscape can deal with the tablet just fine when it's set to default settings, but something goes wrong when non-default settings are applied.

The behaviour is exactly as described: menu's and controls work just fine, but the canvas no longer picks up any input from the pen, even though the mouse and even the mouse for use on the Wacom tablet still work fine.
