I have installed Ubuntu 7.0 64-bit OS on a 64-bit hardware - Hyper Threading enabled P4 processor. Photoshop 7 and Pagemaker seems to be working fine. I installed Coreldraw11 without any problems. But, I am not able to run Coreldraw 11 Once i execute the Coreldraw application, the coreldraw window appears but disappears when the message on the window is Creating Application Environment. I also configured Wine to use Win98 version, but the problem still exists. The log is huge, i will paste the beginning of it. wine CorelDrw.exe err:x11drv:X11DRV_CreateWindow invalid window height -23 err:x11drv:X11DRV_CreateWindow invalid window height -23 fixme:mmio:MMIO_InstallIOProc Global procedures not implemented fixme:wintab32:X11DRV_WTInfoW WTI_INTERFACE unhandled index 7 *** stack smashing detected ***: CorelDrw.exe terminated wine: Assertion failed at address 0xffffe410 (thread 0009), starting debugger...
