Carlos,

The reason why your code doesn't seem to have any effect is the order in 
which you remove the Menu Items. You must always remove them from the bottom 
up -- removing the highest numbered (or last) Menu Item first.

Changing your code as follows, will remove the listed System Menu Items, and 
will also gray-out (and disable) the [X] Close button. But the ALT + F4 
functionality and the other two buttons (Min/Max) will still work.

ApiTitleOptions_(oDlg, cabWIN_CLOSEBUTTON,    .t.)
ApiTitleOptions_(oDlg, cabWIN_ITEM_SEPARATOR, .t.)
ApiTitleOptions_(oDlg, cabWIN_MAXBUTTON,      .t.)
ApiTitleOptions_(oDlg, cabWIN_MINBUTTON,      .t.)

The reason for this is simple: When you remove a Menu Item, the remaining 
Menu Items will be re-numbered. So if you remove Item 3, then Item 4 will 
become Item 3, etc. So your original code removed first Item 3 (the Minimize
option), then Item 4 (which was then the Item Separator), and then Item 5,
which by then didn't existed anymore. So the Maximize and Close Menu options 
both remained in the menu.

The following code will do the same as above -- removing the last four menu 
items -- but it looks a little stranger:

for nItem := 1 to 4
    ApiTitleOptions_(oDlg, cabWIN_MINBUTTON, .t.)
next

Rather than removing those System Menu Items, you might as well create the 
Dialog without the Min/Max and/or Close buttons from the beginning, and/or 
remove the System Menu completely, using the appropriate XppDialog iVars.

For example, using the following:

oDlg:MinButton := .f.
oDlg:MaxButton := .f.
oDlg:Configure()

will remove the Min/Max buttons and gray-out the corresponding System Menu 
Items. This would be considered Standard Windows Behavior, and preferable 
to your method.

Hope that helps.
