Have you tried this,...................BEFORE YOU SAVE, open the Task Manager, (Control + Alt + Delete), go to the Processes tab,  find Bryce.exe, right click on it,  go to Set Priority, and restet the priority for either Above Normal or High. It is important to leave the Task Manager open while doing this or the Priority will be reset to Normal. When you are done, close the Task Manager and the Priority will be reset to Normal. Try this,.......it might work,............it has worked for me on more than one occasion.
