I've inherited form wich size es 1003,734. If I open this form with OpenEdge ABLEditor the size is ok (ScreenShot.jpg).
But now, I open the form with OpenEdge Visual Designer and automatically change the size of window and I don´t know why do this (ScreenShot2.jpg)
The first one is the Design View and the second one the Source View.
You can switch with right mouse -> View Source/View Design.
But without training I would not touch any of this.
