Here's the bit: I have a form with a pageframe control and several buttons outside the pageframe. If I press one of the buttons, it brings up another form with a pageframe control on top of the first one.

1) If I now try to invoke a MessageBox, I have to Hide() the second form or my MessageBox doesn't appear. The speaker chimes, but no window is visible, so I have to Ctrl-Alt-Del and choose Shut Down. As soon as I do this, the window pops up and all is fine.

2) If, from the second form, I pop up a modal form, I get no cursor. If I Hide() the second form, all is fine.

What am I doing wrong?

TIA.
