January 2026
---------------------------------------------------------------------
CCB
1. BUG:
In vfp9 (and vfp7, vfp8), if the Command window is dockable,
sometimes the main Visual FoxPro window is not shown, but the docked Command window is shown.
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
Label4352af ::
mov esi , dword ptr [esi] ;0x004352af : 8b36
mov eax , dword ptr [ esi + 68 ] ;0x004352b1 : 8b4644
test byte ptr ah , 01h ;0x004352b4 : f6c401
