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?

I use Lazarus 1.8.4 on Linux, so far never experienced the issue you
mentioned. What OS were you using? It looks like Win7 safe mode. What
were you doing before that thing happened? Were you in the middle of
compiling or typing the code?

Please provide more information, the most important is the steps to
reproduce the problem. So we can test it.

I 'm on Windows 7 but not in safe mode.
I don 't do anything special before this happens, I just go from
Firefox to Lazarus and vice versa.
Nothing else.

Have you tried pressing F12 inside the form1 editor window (press it a
couple of times)?Quote from: panoss on August 03, 2018, 05:36:35 pmI

erm that makes no sense there are two major reasons for this
  1) the form designer is outside the visible range, your first post
should have taken care of that
  2) The form designer is closed (pressing the x on the top right
corner) my suggestion should take care of that.

Switching between application should have no effect what so ever, if
it does then something is wrong either with your keyboard or your
system.

designer is the Lazarus IDE), so what do you mean that it 's outside
the visible range?

no, the IDE is separated in to 3 main parts
1) the code editor,
2) the Form designer (ee the form in design mode where you can place
and move controls)
3) the inspectors and other floating toolbars (object inspector,
project inspector, component toolbar etc)
