console output

The application runs flawlessly while controlled with the mouse only or with a
combination of keyboard and mouse input simultaneously. 
But upon pressing any button on the keyboard alone, with the only exception of
the F* keys and the NumLock, the application freezes until focus is changed to
another window and returned to the application window. 
After returning focus to the application window Sculptris continues to work  as
if no keyboard shortcut was pressed. The only exception to this are the square
brackets and the numpad Del keys, which have the effect of
increasing/decreasing the brush size. They too do freeze the app, but the brush
is larger/smaller after returning to the app. No other keyboard shortcuts (most
notably ctrl-z - undo) are not working. This makes the application unusable for
serious work, because many things are controlled only via keyboard and are not
present in the UI.

There is nothing on the console, except the following three lines:
