Render image (or part of it) remains on the screen after exiting Render Mode, or, program crashes with a Windows error message when attempting to calculate and/or access Render Mode, or, images in Roadway Optimizer and/or Room Estimator do not look right (e.g. text is partially displayed).

These problems are most likely caused by the graphics card/driver not properly handling the graphics data sent by AGi32.

The easiest resolution is to disable Hardware Acceleration in Render Mode and/or in Dialog Viewers (Tools-System Settings-Advanced Settings). Be sure to Save Settings as Startup Default. This video will show you how: Another possible resolution is to upgrade your graphics driver.
