#23 Not working with N-Trig WinTab driver under Windows 8

[Ramon Talavera]

When launched in a Windows 8 system (fujitsu stylistic q704) with the latest N-Trig pen drivers and N-Trig's Wintab drivers (32 and 64 bits dll tested) the demo application crashes as soon as the stylus touches the screen. This is probably happening in every system using N-Trig, Fujitsu, Lenovo and Vaio.

N-Trigger WinTab drivers can be downloaded from:
http://www.n-trig.com/Content.aspx?Page=support_home
(left corner of the page has links to 32 and 64 bits)

Tested with almost all versions previous to jpen-2-121204 (included)
I suspect there is a problem when reading low level event's data package.

Program Log follows, it seems to have detected WinTab without problems, but the program crashes as soon as the pen touches the screen.

[Nicolas Carranza]

hi Ramon, looks like it crashed when making a jni call... could you please provide me the hs_errXXX.log file generated by the jvm ? (What does it do when pressing the "Depurar" button?)

Thank you for reporting this bug,
Nicolas

Launching with:
java -XX:ErrorFile=java_error%p.log -jar jpen-2.jar

But I get no error files at all (the application fails as it did before). Am I launching it correctly?
