Well, I have never been good at promoting anything, but it is shortly 
mentioned in the feature list on my web site.

> What did you do in the program to enable this interface?

It is called OLE (Object Linking and Embedding). In short Graph is an 
OLE server and implements some interfaces which a client (for example MS 
Word) can use to interact with Graph. This way Graph can store data 
inside documents created by other programs.

You can find more information in the help under OLE server/client.

Same problem here (Wine 0.9.21), Graph fails to write the version number
on the saved files and on the ALT+F1 window, this is an example saved file:

;This file was created by Graph (http://www.padowan.dk)
;Do not change this file from other programs.
[Graph]
Version = ????Ô’
Build = 270
MinVersion = 2.5
OS = Windows XP 5.1 Service Pack 2

[Axes]
xMin = -10
xMax = 10
xTickUnit = 2
xGridUnit = 2
yMin = -10
yMax = 10
yTickUnit = 2
yGridUnit = 2

Yes, it looks like Wine is having trouble reading the version number. 
You can use the beta version of Graph 4.2 at:
http://padowan.dk/graph/SetupGraphBeta.exe

It will ignore the Version field in the grf file if it is invalid. I 
plan to look into why Wine cannot read the version number and find a 
better solution to the problem. But it is not easy to debug a Windows 
program under Linux.

You could ask for help on Wine ML or IRC channel.
I don't have much C++/Windows experience, I can't help.

I just installed the beta version and now the application doesn't start,
I only get an error message when running Graph: "Menu index out of range.".

Yes, I might do that. I could also look in the documentation for Wine. 
Funny enough it looks like it can read the build number but not the rest.

You are right, I can reproduce it. It looks like it only happens when 
you select another language than English. I will look into it.

I can confirm: using english language fixed the problem here (I was
using italian).

I have now located the cause of the problem. It is a workaround for a 
bug in Windows XP that apparently doesn't work well under Wine. I don't 
know exactly why. I have updated the beta version to just ignore the 
error and that seems to work fine with all languages:
http://padowan.dk/graph/SetupGraphBeta.exe

It isn't working with italian language, I get an error message:
"EAccessViolation.". With english it works fine.
