I posted some code in a separate message a few minutes ago, I just wanted to point out that the code runs error free when compiled in Release mode, and works as it should when saving the memory block to a file (and viewing it in a text editor). So the problems only appear in Debug mode on VC8/Vista 64. I can live with that I guess hehe.

Hi, Andy!
It's a little difficult to discuss the problem when the only information available is that you're using wxSocketClient. The problem may be further up the line. With only this one piece of information, one must assume that everything before the call to wxSocketClient methods/functions to retrieve the messages is performing correctly and that everything that was needed to be done before the wxSocketClient transactions was done!;)
It's much, much easier to talk about problems and issues if you attach your project (or a facsimile) to a posting you make from your email client (Yahoo! Groups does not do attachments!:-< ).
If you're using DialogBlocks, it's even easier to "share" as all one must needs do is attach the .pjd file (DialogBlocks project file). This will allow the receiver to build and run on their own system quite easily.
Any attachments should be in archive format (zip or other) to reduce size (.pjd's are quite large, but very compressible!;) and to make it more likely that the receiver's email client/antispam won't prevent its delivery.
The only thing I can do, from the information available here, is make a "swag" at a possibility. It appears that an "undocumented procedure" in wxSocketBase has to be performed first. I put it in quotes because it actually is documented, but only "before" the fact. That is, most wxWidgets "Base" classes are not intended to be used, only derived from. Hence, a developer (like me!;) doesn't often look at base classes in wxWidgets classes. The assumption being that the derived wxWidgets class is/has taken care of any parent class necessities.
In looking at the wxSocketBase documentation I see a blurb:
>>>>>
wxSocketBase is the base class for all socket-related objects, and it defines all basic IO functionality.
Note: (Workaround for implementation limitation for wxWidgets up to 2.5.x) If you want to use sockets or derived classes such as wxFTP in a secondary thread, call wxSocketBase::Initialize() (undocumented) from the main thread before creating any sockets - in wxApp::OnInit for example.
<<<<<
Now, it does say this is for wxWidgets up to 2.5.x, but it's the only "swag" I've got right now!:-( If it doesn't help, you might like to consider archiving an example and attaching it to an email client generated post.
HTH:
thx,
Dave S.
