I can consistently put DrScheme in a bad state by the following:
1) Open a fairly large file (so syntax checking takes time)
2) Make a change
3) click Check Syntax
4) click Save -- before checking is complete.
It seems as soon as syntax checking completes, an internal error is
signalled. The error varies, but it always occurs. Here are a couple:
1)
sequence-contract-violation: negative: method delete cannot be called,
except in states (unlocked), args 0 360

After this, the definitions window is broken. I cannot reposition the
cursor, type text, etc. I can click Save but it doesn't go away. Run
and the interactions window work fine.
This is on 4.1.900-svn21may2009 [3m], Mac OSX, ISL/lambda.
Should I be submitting bug reports, or emailing this list since this
concerns the release candidate?
