Violation Error on ShowMessage()

[Hervé Wilquin]

Hi,

I'm building an application with BCB4.
A click on a button launch an ShowMessage("ok");
If I open this application on a server connected with a Remote Control Soft
(Unicenter Remote Control of Computer Associates International)
Then close the connection and get reconnected
I get an "Access violation at adresse 40050738 in module 'vcl40.bpl'. Read
of address 00000004" on click instead of the message box.
I get the same result with a Form->Show(); action instead of the
ShowMessage("ok");
How can I get around this error?

You are trying to access a class member via a NULL pointer somwhere.
