Now that's very interesting. I did know about the general behaviour, for 
example the exe name (not full path) thing, because a couple of simple tests 
confirmed it empirically, but I did not know where the information was 
stored. I was certain it would be in the registry somewhere but I had not 
actually looked for it. Thanks for that piece of information. It might be 
interesting to now look at how the size and window state information is 
encoded, which at least at first sight seems to be fairly straightforward. 
Clearly the exe name is contained very simply in bytes 0000 to 0207 (the 
name followed by a load of trailing zeros) and the data itself is contained 
in bytes 0208 to 024F. The dialog window state (maximized or normal) is 
represented by the last four bytes (0000 for normalized and FFFF for 
maximized), a fact which can also be confirmed empirically, and it looks as 
though the normalized size should be easy to figure out as well. There is 
space for lots of other stuff of course, but I haven't looked into that yet. 
Thanks for the info regarding the location. This should help Bob Butler to 
pin down his own specific problem.
