[plt-scheme] DrScheme startup error: unbound variable in module in: -reset-console

Hi folks,

Starting up DrS 300 on Windows XP Pro I get an error:

...ents and Settings\grettke\Application Data\PLT
Scheme\360\collects\schemeunit\drscheme-ui-tool.ss:80:13: compile:
unbound variable in module in: -reset-console

 === context ===
c:\program files\plt-360\collects\drscheme\private\tools.ss:169:12
c:\program files\plt-360\collects\drscheme\private\tools.ss:70:6:
load/invoke-all-tools/collections

I haven't done anything recently to provoke this (like add custom
tools or touch the source code).

Does that error mean anything to you guys?
