Unhandled exception when resizing a column in Projects

[hexenwerkgames]

At first, thank you very much for this useful tool!

One reproducible bug I found is an error message I get - every time I resize a column in the Projects tab.
I already commented this at the commit, but since I'm not sure if that's the right place, I'm adding it here as an issue, too:

"System.ArgumentNullException: Der Wert darf nicht NULL sein.
Parametername: collection
bei System.Collections.Generic.List1..ctor(IEnumerable1 collection)
bei UnityLauncher.Form1.gridRecent_ColumnWidthChanged(Object sender, DataGridViewColumnEventArgs e)

bei System.Windows.Forms.DataGridView.OnBandThicknessChanged(DataGridViewBand dataGridViewBand)
bei System.Windows.Forms.DataGridViewBand.set_ThicknessInternal(Int32 value)
bei System.Windows.Forms.DataGridViewBand.set_Thickness(Int32 value)
bei System.Windows.Forms.DataGridView.EndColumnResize(MouseEventArgs e)
bei System.Windows.Forms.DataGridView.OnMouseUp(MouseEventArgs e)

bei System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Hope this helps. I'm using the "4 Months To Go" Edition 20, whatever this means.

can you try this build,

(it has some default values added to the widths so shouldnt be null)

The gridColumnWidths xml in AppConfig.xml was indeed missing and caused the error for me as well (pulled 5 minutes ago).
I have created a patch and pull request to fix it.
#42

Hi, your 21beta build works. I have also added a patch to the pull request (reverted the old one and added a new one). Default values are no longer needed.

Btw.: To propery reproduce this error you had to delete the data in "%AppData%..\Local\UnityCoder.com". I guess that's why it worked for you. Once you have saved the data it will just work every time. Maybe we should always delete the data in "%AppData%..\Local\UnityCoder.com" to make sure tests are done against a "clean install" environment. Maybe VisualStudio can do that automatically?

@Raebyn can test the latest build if it works for you

@geo-at-github ok thanks! yeah would be nice to test with clean settings inside vs, didnt find anything useful related to that yet..
