Common dialogs

Note: This is a 16-bit app.  In AppStudio I created a dialog box that looks like a common open file dialog but has some extra controls.  The class that handles this dialog is derived from the CFileDialog class.  The problem is this, when CFileDialog::OnOK() is called from my ::OnOK() member function, the dialog does not disappear.  However, CFileDialog::OnCancel() does cause the dialog to disappear.  Here's something strange:  if I use CDialog::OnOK() the dialog disappears like expected.  There is one problem though, eventually Win95 runs out of "16-bit" memory and no more common dialogs will display, not only my app, but any 16-bit apps.  The ::DoModal() function returns a CDERR_MEMALLOCFAILURE error.  Any clues as to why CFileDialog::OnOK() does not work and why CDialog::OnOK() is not cleaning up properly??

Try increasing the stacksize in your module definition file. It needs to be at least 8196 and typically more. I would suggest 12K.

Wouldn't increasing the stack size just allow me to use the dialog a few more times before the memory error occured again??
