In the beginning I used to struggle with cleanly closing a project and loading another.
Just open a new project right away (menu
Project > Open or even
File > Open). The old one will be closed automatically. You will be prompted to save it if there are any changes.
it would be nice if the IDE remembered the last size used when the project-Close dialogue is opened.
I agree, so I wrote a
patch. After the developers accept it, it will be in the new version of Lazarus.
While I was making the patch, I also found a small
bug in saving the size of the options dialog ))
