You are quite right. Debug shows no trace of the form.

And yet - if I write a simple program to open and release the form by name it works fine and the Windows list shows no open forms. But if I run my program the form does not show up in debug but it shows in the Windows list and I can click on it and there is my form.

Is this a bug or sime sort of memory problem?

Thanks for all your help
