In Lazarus editor, the form at the beginning appears just fine.
After a while, it dissapears!!
I can see the Lazarus IDE, the object inspector, the Messages window, the Source editor displaying the code of the form...but...not the form. (take a look at the attached file)
I try Window->Form1, nothing.
I try Window->center lost Window->form1, nothing!
I have to close Lasarus and restart it for the form1 to reappear!
How can I fix this?
