Hi

When I use the Apollo4P platform and set EW_USE DOUBLE_BUFFER to 0, an error will be displayed. Is it not supported?

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

Initialize Touch Driver...                   [OK]
Initialize Memory Manager...                 [OK]
Initialize Graphics Engine...                [OK]
Initialize Invocation Queue...               [OK]
Create Embedded Wizard Root Object...        [OK]
Create Embedded Wizard Viewport...           [ERROR in ewextgfx.c:281] Invalid double-buffer address!
EMWI ERROR: code: 150
For details please visit https://doc.embedded-wizard.de/errors
[failed]

Hello,

changing the macro EW_USE_DOUBLE_BUFFER requires the complete source code of the Graphics Engine to be recompiled with the new setting. As such it works for customers who have licensed the 'Professional' edition only. For customers using the 'Small Business' edition or users working with the Free edition, the macro will not have any effect or will cause runtime errors.

Best regards,

Manfred.
