I have just uploaded a new release of ZStyleSheet (Version 4.2.4) which fixes a rather anoying ZODB bloat issue. It seems that some code I added to delete an attribute of an object if it was found, was writing a transactiong to the ZODB even if there was no work to do... oh well. This bug was introduced in version 4.2.3 (In fixing another bug), so I strongly recomend you upgrade, especially on high volume sites. Sorry if this caused anyone any problems.
