[VFP] Modal Window not displaying

[jkirstaetter]

This is the first I've come across this problem, which seems to be specific to this ActiveX control.
...
It's almost as if the ActiveX control is preventing the window from displaying.

Try to fix the ActiveX.  

Code:

*========================================================================================
* HWND des ActiveX Controls aus dem Activate des Formulares heraus aufgerufen werden.
*========================================================================================
Function ActiveFix
LParameters tnHWND
    Declare Long GetParent in Win32API Long
    Declare Long EnableWindow in WIn32API Long, long
    EnableWindow( GetParent(m.tnHWND), 1 )
EndFunc
