Dev Info
--------
I am using VFP6 service pack 3 on Win98, the application is n tiered using a business data object with several layers of subclassing to every control.

Problem
-------
When I call a new form from this particular main form and then return to the main form, all the objects on the main form have jumped up by a line. In fact there is a white line at the bottom of the form. The original objects are ghosted in their original positions with the now incorrectly positioned objects above/over them. OK, so what I want to happen is for the objects to remain where I put them in the first place on the main form.


Additional Info
---------------
The new form is called from a button click event with the form call method residing at the form level object. Another button on the form does the same form call method, but to a different form and does not demonstrate the same erroneous behaviour. I realise that this probably means the called form is at fault, I just don't know where to start looking. The load of the new form just creates some business objects and has no affect over the form display settings that I am aware of

Lockscreen and Refresh states
-----------------------------
The calling main form has lockscreen set to .T. before the new form is called and a refresh is issued before the main form screen is unlocked, after the called form has been destroyed.

Any help would be greatly appreciated.
