Form wsMaximized bug...

[jojo86]

Hi, I'm french, and i need your help!

I have a problem with many applications build with lazarus.
In my firm, we use a program build with lazarus.  Some users report a bug.

In Lazarus, i set the windowstate of my form to wsMaximized. When the program is starting, the form is maximized and the screen become transparent. I can't see controls on the form, but i see the behind window.

My form stay transparent ...

i don't unsterdant it's incredible. Do you have an idea? (many user uses dual screens...)

Thank you very much.

Check if all computers with problem have the same graphic type vendor. If they do, update drivers and retest. If there is still a problem then change the graphic card type and repeat tests. I have seen some Delphi applications behaving strange on some graphic cards in the past. You can also check free resources on these computers with some tool. Maybe there aren't enough resources for drawing widgets. It used to be a big problem on Win9x, but less of a problem on WinNT+.

Hello.
I had the same problem...

That solves the thing for me ...

Code: [Select]

procedure TMiximazeCrash.FormCreate(Sender: TObject);

begin
  application.ProcessMessages;
  ...
end;

Hi,
Realy the same? Could you post a screen shot for other users?

I'll try the processmessages. I must insert this action in the form.create?

Thank!
