Zabbix 1.5.3 web mon graphs- changed name of check and lost history

[ericb]

behavior as expected, i think.

I have a web mon that has 3 stages of the check

everything was running great 3 nice stacked graph etc for response times

I then have changed the name of a 2 of the checks and now we have lost the history graph information of the 2 we changed the name of.

new data is there for the newly changed graphs.
