What steps will reproduce the problem?
1. Open the last moose release (4_0-beta-5) in Windows
2. try to import a project using the function "Import Java sourceFiles with inFusion"

Seems that "ExternalWindowsOSProcess class>>command:" of OSProcess doesn't properly
work 
in windows. In mac i never have problem using it.

For sure the specific command line for Windows have to be create because actually there
is just 
the Linux\Mac version. Anyway the problem is different because even this command in
Windows 
doesn't work:

OSProcess  waitForCommand: 'cd "', 'C:\Documents and Settings\Administrator\Desktop\moose-
suite-4_0-beta-5\moose-suite-4_0-beta-
5.app\Contents\Resources\inFusion727\tools\inFusion', '"'
