Memory leak update
The memory leak seems to affect Windows XP as well, so I can only assume that this is a problem on all platforms. You are only affected if you run under -Dteppefall.chrome=false and you can probably stop the problem by setting -Dteppefall.cursor-monitor=false.
Example:
java
-Dteppefall.cursor-monitor=false
-Dteppefall.chrome=false
-Dteppefall.override=true
-Dswing.defaultlaf=com.teppefall.ds.look.TitaniumLAF
-jar darkstarlayout.jar
