WGT 5.0 Troubleshooting Guide
-----------------------------


Problem 1:      When I set the palette with wsetpalette, all the colors
                remain black.

Solution:       You should have set the palette beforehand with wsetrgb or
                wloadpalette.  If you have loaded the palette, make sure
                the file is in the correct directory.

----------------------------------------------------------------------------

Problem 2:      When I use wfade_in, wfade_out or other palette functions,
                "snow" appears at the top of the screen.

Solution:       This screen disturbance occurs when you change many palette
                colors at once on poor video cards.  Try settings fewer
                palette colors at once with wsetpalette, or use a larger
                delay if you are fading the colors.

----------------------------------------------------------------------------

Problem 3:      When I use wfade_in, wfade_out, or other palette functions,
                the palette never changes.

Solution:       Some palette routines require you to call wsetpalette to
                actually change the colors.  These kinds of functions
                just change the values in the palette array but do not
                tell the VGA card they have changed until you call
                wsetpalette.

----------------------------------------------------------------------------

Problem 4:      When I load in a picture and a palette, the picture does not
                display on the screen.

Solution:       WGT's image functions load all images into a buffer, not
                onto the screen.  This means you will need to display the
                image on the screen using wputblock.

----------------------------------------------------------------------------

Problem 5:      When I load in a picture and a palette, the palette is
                not correct.

Solution:       You must call wsetpalette to use the palette from the image.

----------------------------------------------------------------------------

Problem 6:      I am using wputblock or another image display routine and
                all I see is a jumbled mess on the screen.  

Solution:       The image you tried to display was not loaded or allocated. 
                If you try do display a pointer which is not initialized
                it will display whatever is in memory at that point.

----------------------------------------------------------------------------

Problem 7:      Some of the example files do not seem to work right, and
                I must use a control break to end.

Solution:       Many of the examples programs require a mouse to operate.
                Others require a certain keypress or mouse button to be
                hit before ending.  Make sure you read the introduction
                before each example to see what keys you can use.

Problem 8:      When using a SVGA program, only the top third of the screen
                is updated.

Solution:       You must run a VESA driver before using the program.     
                The problem lies in the bank switching code for you
                particular video card.  Without a VESA driver, WGT doesn't
                know how to switch to other banks of video memory and
                output is limited to the first 64k of the screen.
                Running a TSR such as univesa or uniVBE beforehand will
                fix this problem.

----------------------------------------------------------------------------

Problem 9:      When using the mouse routines or within the Map Maker and
                Sprite Editor, the mouse cursor hotspot seems off, the
                cursor image is incorrect, or the mouse movements are
                jerky.

Solution:       The mouse driver you are using is not fully Microsoft 
                mouse compatible.  Cheaper mouse drivers do not define
                the default settings the same way and can cause various
                problems with mouse routines.
