anyone expert in terms of batch file configuration? I'm attempting to use the following windows cmd commands to switch between different wallet address using one single batch file. However it seems to me that once the first phoenix process has started, the timeout command following is no longer working. Any suggestions as to why?

:wallet1
echo Starting Mining Process
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

PhoenixMiner.exe -pool us2.ethermine.org:4444 -pool2 us1.ethermine.org:14444 -wal -gpus 1234567 -pass x -logfile *
timeout /t 60 <---stopped here>
taskkill /im PhoenixMiner.exe /f /t
goto wallet2

:wallet2
echo Starting Mining Process
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

PhoenixMiner.exe -pool us2.ethermine.org:4444 -pool2 us1.ethermine.org:14444 -wal -gpus 1234567 -pass x -logfile *
timeout /t 60
taskkill /im PhoenixMiner.exe /f /t
goto wallet1
