>>>I have a situation where instead of one large form, I'd like to have a bunch of smaller forms on the screen at once. This would allow the user to move them around or minimize them individually. All these forms are related to each other, so when the user does something on one form, it needs to affect the other forms.

The simplest oApp can be created in Main.Prg (first module of your app):
oApp=createobject("clApp")
do mainform
read events
return

Define Class clApp as Custom
.myform1=.Null.
.myform2=.Null.
...
EndDefine
