Hi guys.

I'm using a post method in my application (Loggin to Google Adsense
Server). This usually works fine, for most users. I suddenly have a user
that reports an error. I gave him a debug version, and got this -

Access violation at address 004062D0 in module 'AdSenseLog.exe'. Read of
address 00000004

Here's my code -

  Params := TStringList.Create;
  AddressStr := '...'
  TempStr := MainForm.IndyHttp.Post(AddressStr,Params);

The error occurs in the post line - I never get to that final log file.
I get an exception - access violation.

Any ideas what might cause this??
