Your miner works on C29 for a few minutes then forces my rig to switch to Cuckarood29 although the fork hasn't yet happened!!
:-(
Did you use config file to start?
Try add
"grin29-fork-height": 262080,
to the json file.
Or start with cmdline options.
Had this same issue on HiveOS. Added this to the Extra config arguments - "grin29-fork-height": 262080
Its working fine now,
Thanks
Will add a option to auto generate a json file in future versions.

Can you be more specific?
A screenshot with both Miner cmd windows and task manager windows will be good help.
