I am posting again hoping that someone could help.

I have a form (or several forms), which are created within the MainForm. 
When setting "WindowState     = wsMaximized;" the whole form doesn't 
maximize within the MainForm as it used to in BCB 5, but also it is 
larger (I can't see it all) and I can't move it. I double checked and 
made sure that with BDS2006 this form has all the properties the same as 
when I open the project with BCB 5. I realize that in BDS2006 a form has 
a few more properties, but it is unclear what is going on. If I set 
Align = alClient and Autosize=true I get the form maximize within the 
MainForm but if I restore it I still can't move it or resize it. When I 
do the resizing with the mouse the image withing the form resizes but 
the form borders remain where they were when WindowState     = wsMaximized.

Please help, all these behaviors do not occur when I compile the project 
with BCB 5. Because of that I am still not using BDS2006.

Thanks
