There appears to be an issue with the Workflow designer in v3.0.0.2970 that is preventing the .xoml file from being saved. The .xoml.cs file is being saved correctly but when SD tries to save the .xoml file it generates a 0 byte file then pops up an exception window or a window saying that there may be a permissions error.
Stack trace is included below:

***Update: The message that pops up when I try to save the file
Can't save file Workflow1.xoml under C:\Documents and Settings\lewisd2\My Documents\SharpDevelop Projects\ConsoleWF\ConsoleWF.
Choose another file name or check if the directory exists and that
you have write permission in that path and file. (maybe a write protection problem?)
