---------------------------------------------------------------------------------------------- [ENHANCED] VFP 9.0 FIX - SAVE NEGATIVE COORDINATES FOR THE MAIN VISUAL FOXPRO WINDOW January 2024 ---------------------------------------------------------------------------------------------- CCB 1. BUG: In VFP Advanced 32-bit, we can set the saving negative coordinates for the main Visual FoxPro window in the windows registry: HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\10\Options\SaveDesktopNegativeCoordinates. In VFP Advanced 64-bit, we can set the saving negative coordinates for the main Visual FoxPro window in the windows registry: HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro64\10\Options\SaveDesktopNegativeCoordinates. 2. CAUSE: There are some BUGs in the following code. 3. RESOLUTION: We can write some code to fix the BUG.
