C# - Please help: Url detection stopped working suddenly

[latitude]

Have had a few questions here but no replies so far so thought id give it one more go: Im working on a textviewer/editor and have used autodetect url on it, and it has worked fine. But somewhere along the road it just stopped working when opening files by clicking on them in explorer, works fine with drag n drop and by opening via filemenu. Code I use for opening program by clicking on files in explorer and where autodetect is NOT working is as following:

public static void Main(string[] args)
        {
            if(args.Length > 0)
            {
                Form1 frm = new Form1();                
                System.IO.StreamReader myFile = new System.IO.StreamReader(args[0], System.Text.Encoding.Default);
                string line = "";
                line = myFile.ReadToEnd();

An example of opening file by menu which works fine with autodetect:

if (openFileDialog1.FileName != "")
                {
                    FileStream file = new FileStream(openFileDialog1.FileName, FileMode.Open, FileAccess.Read);
                    System.IO.StreamReader sr = new System.IO.StreamReader(file,System.Text.Encoding.Default);

ANY help is appreciated!!

You've probably had no replies because this is the C/C++ board. C# is a .NET language and you should probablt post your question over there.
