SQL query _slow_ - Mailing list pgsql-sql

I have a few SQL query's that are taking in the range of 30-60 seconds
to complete. They are searching tables that are no larger than 120 rows
with I believe 7 columns of data each.
Any ideas?
The SQL statement is below:

SELECT tblClientInfo.fName, tblClientInfo.lName, tblClientInfo.phoneNum,
tblClientLocation.locationName, tblTroubTick.TroubTickLastUpdate,
tblTroubTick.hoursInvested, tblSupportPersInfo.fName,
tblSupportPersInfo.lName, tblPriority.priority, tblTroubTick.assetID,
tblTroubTickStatus.troubTickStatus, tblTroubTickProblem.troubTickProblem

FROM tblClientInfo, tblTroubTick, tblClientLocation, tblSupportPersInfo,
tblPriority, tblTroubTickStatus, tblTroubTickProblem
WHERE  tblTroubTick.troubTickStatusID <> 7 AND
tblClientLocation.locationID = tblClientInfo.locationID AND
tblTroubTick.clientID = tblClientInfo.clientID AND
tblTroubTick.supportPersID = tblSupportPersInfo.supportPersID AND
tblTroubTick.priorityID = tblPriority.priorityID AND
tblTroubTick.troubTickStatusID = tblTroubTickStatus.troubTickStatusID
AND tblTroubTick.troubTickProblemID =
tblTroubTickProblem.troubTickProblemID;

Thanks for any help!
