For a fresh install of Lazarus/FPC/LAMW (using FPCUPdeluxe) on Linux and Windows, I am getting an error when I do the following:
1) Close Lazarus and reopen it.
2) Create a new LAMW GUI project
3) Try to place controls on the form.
For example when I try to put a jButton on the form I get an error message: "Error moving component JButton1:JButton". (and the jButton never shows up on the form.)
But if I save the project and re-open it, the error message is gone and it works as expected. If I open a demo project, they also work properly.
Please see attached error message.
