Strange pattern with a dangling pointer in TProc

Hey.

Almost any class implementing a Tortoise Proc "user command" has a pattern like the following:

void CClass::Execute()
{
   CSVNProgressDlg progDlg;
   theApp.m_pMainWnd = &progDlg;
// create dialog, run modal loop, exit
}

When the function exits the dialog object is destroyed, but m_pMainWnd in the global object is kept unchanged and now stores a dangling pointer. Is there any reason for that? If not - I could send in a fix.

Best wishes.
Dmitry.
