I've just tried to update on my slave:
Reconfigure Permissions in master database? (yes,no) [no]: yes
ERROR: Unable to set rights of user in master database: dbispconfig Error: Table 'dbispconfig.sys_remoteaction' doesn't exist
errr... yeah. Ideas? (That's after giving it the master server details - why do you need to put them in again if it has them in the config file?
