ShowModal should disable parent window or what?

Question

Hi,

I am using wxwindgets 2.8.7 on C++.

There is a parent frame which is derived from wxMDIParentFrame and from that frame, there is a call to a message dialog with ShowModal.

... dlg->showModal(); ...

In other parent windows, showModal disables the parent window but in this mdi window, it is still enabled somehow.

I want that showModal call block user input in parent windows which is derived from wxMDIParentFrame.

Any idea?
