Sudden World Editor Issues - Stock or my Box?

I noticed that there was this in the console on startup

UDP initialized on port 0
 % - Initializing Tools
...
 % - Initializing World Editor
tools/worldEditor/scripts/EditorGui.ed.cs (1221): string always evaluates to 0.
...

And suddenly started getting various problems with the World Editor -> Level functions, inability to select/create a level object. Pretty sure I haven't been fiddling with this stuff.

Creating a New Project and replacing the tools section of my original appeared to sort out this issue.

Anyone else see the above line in their startup console? Or had issues concerning
tools/worldeditor/gui/WorldEditorSettingsDlg.ed.gui?

Not sure if it's my box - did have Chinese haxxorz try to get on it last week but foiled them with the v.1eyeBall (thanks a lot AV and Defender...), no damage done (apparently).
