Yes, you are right. I was trying create a complicated solution to a
simple problem.

My app allows to draw vectors and I'm adding the ability to add text to
the drawing, in a similar way as CorelDraw or Inkscape. After the user
clicks on some point, a TEdit was drawn and the user can start typing. 

I solved the problem by showing a dialog with a TMemo to let the user
type. This way the actions of the main form aren't involved.

Thanks.
