Fedora 17, 4Core, with split screen 2 at 1920 x 1080 (16:19) giving --> 1920 (High) X 2160 (wide)
via terminal lauvch gives...
[root@ws1 eschalon_book_3_100_linux_bg]# ./eschalon_book_3
Unable to calculate tex size
#

SweetHome3d gives another take on this...
AT Launch of SweetHome3D...
If the Linux Terminal is in the Left Monitor -----> CRASH
if the Linux Terminal is in the Right Monitor ----> Works Great... Modify, file Save, Reload all work well....#

however
OpenOficeOrg ... never a problem...
Thunderbird... never a problem...
FireFox.. never a problem
I have NOT been able to Run ESCHALON BOOK II reliably either...
Book2 loads, runs like a dog, then crashes after about 3 minutes.. (I have to use Windowed Mode)
any advice on tweeks to the Screen Driver (Fedora) that might help?
