>Turns out that shapes were everywhere. We removed the shapes from the form. But I would like to know what your fix was.

Just a sec, let me find an old app to see what I did to fix it, it's been a while. Okay:

In a form Init, try putting code for each shape like this:

this.shape.backcolor = this.textbox.backcolor

The textbox can be any normal editable one you want, or even a hidden one. But I'm assuming you have one available somewhere?

The problem is apparently caused by a bug in the shapes where the transparency doesn't work quite right. Hopefully, this is the same problem I had.
