Hello.
I have installed Bryce 5 (Corel version) under CX Pro ver 4.1 on MEPIS Linux, 2.6.7 kernel, Debian Unstable, KDE 3.3.0 window manager with NVIDIA graphics drivers on a PII-450 with 786Mb RAM.
Installation went without a hitch by just pointing CX to the correct CD-ROM drive on the machine. I accepted the default install parameters and the script worked just like it does under Windows 2000 Pro. I started Bryce 5 by clicking on the "Windows Applications --> Bryce 5 --> Bryce5" button under the KDE menu. The application started perfectly with no modifications to the link.
Once the program started, I tested the mouse functions as described in the previous posts. At first I could not get the top flyout menu to activate. On a hunch, I tried the "Alt-F" key combination used in Windows to drop the flyout "File" menu. The menu did not appear, but when I ran the mouse over the area where the menu should be, the flyout appeared under the mouse cursor. Running the mouse right and left along/near the top or the screen caused all the menus to appear one after the other. All selections appear to be available, including Ctrl-Q to quit the program. Hitting the Alt key again seems to hide the menu selections from the mouse.
The material editor was the sticking point for me. When I tried to load a JPG from the hard drive, no selection window/dialog appeared and I was forced to kill the program at that point.
From what I have seen by playing around and activating control functions, the native Bryce controls all seem to be accessible and work normally under CX as they do in Windows. The sticking point seems to be when you call for an Explorer window (Menu, Open dialog, Save dialog, etc.). The window/menu may or may not appear. Depending on what you are doing and where you are in Bryce, this may lead you to have to kill the program.
I am experimenting with other shift, ctrl, alt, and mouse click combinations to see if the Explorer windows can be "forced" into a visible mode or killed if they are invisible. (Kinda doubt it, but who knows, I may get lucky.)
BTW, Bryce 5 under CX Pro 4.1 renders pictures quite nicely. As long as you don't get behind one of these invisible Explorer windows/dialogs, the program works great.
Hope this helps folks out in their "quest" to get Bryce 5 running.
Best Regards
