Many thanks for your lengthy reply, but unfortunately no COMM or Active-X controls being used.
Cheers. -----Original Message----- From: delphi-boun...@elists.org [mailto:delphi-boun...@elists.org] On Behalf Of Cord Schneider Sent: Monday, 29 June 2009 8:54 p.m. To: delphi@elists.org Subject: RE: App hanging during load Ross, You wouldn't happen to be using any ActiveX/COM controls in your application would you? We recently had a similar issue where our application stopped working for one of our clients after they applied a Windows update (http://support.microsoft.com/kb/956572). In a nutshell, our application late binds to a DLL that in turn, makes a call to CoInitialize(). We found that deleting the DLL and copying it back to the same location fixed the problem and we suspect that it has something to do with Windows' caching of the DLL and the new (stricter) security restrictions on COM applied by the update. If our application was installed /after/ applying the Windows update, the problem did not manifest. I hope that this helps you track down your issue.

I haven't yet tried debugging the FormCreate procedure as yet, but one user with this problem managed to resolve it. In their case Windows had installed some Windows Updates, and the problem occurred after this. They resolved it by restoring Windows to an earlier restore point. My app then loaded up fine. They then let Windows install all the updates again, and my app is still loading up fine! Go figure! I'm wondering if anyone has come across anything like this before and what it could be.
