After installing DrScheme and playing with it for a few minutes I was able to get it to hang with an error similar to the following error. standard-module-name-resolver: collection not found: “texpict” in any of: ()
=== context ===
The fix is to go under C:\documents and settings\Your username\Application Data\PLT Sheme and remove the file pref.ss
If I figure out what I did to produce this file in such a state and post that as well.
