The problem is triggered by a feature in poclbm I suspect most of the users don't care at all - detecting if a real block is found if mining against a pool. The feature was introduced back in July 2011 and was fixed twice even before being released. Apparently, the fix was not good enough and with the last difficulty adjustment the problem showed up again.

I sincerely hope it is really fixed now. Latest github should be OK. I plan a windows binary release for today.

Can a pro show us noobs how to implement the fix? I'd be happy to throw a coin or two someones way for a quick tutorial on getting it back working correctly.

You can see in BOLD, pull from git if you are Linux user, wait if you are windows user for binary release.

How will Windows users get the update if we're using GUIminer? Do you we have to re-download it? Or will it automaticlaly push after we restart either the computer or the miner?

You'll definitely have to redownload whatever file was modified. I see no reason why any other way would make any sense.

Windows fix out yet? And for those of us with GUIminer, do we have to request an update to GUIminer? Or can we simply install the latest of polcbm?

Anyone know how that can be used to fix the GUIMiner?  Just copying the files from poclbm_py2exe_20120205.7z into the guiminer directory doesn't work.

I don't think you can copy the contents of poclbm_py2exe_20120205 to guiminer...

Try this: extract poclbm_py2exe_20120205.7z using 7zip to c:\poclbm_py2exe_20120205\
then create a text file in c:\poclbm_py2exe_20120205\
paste this updated example in it:

start "GPU1" /AFFINITY 1 /D"c:\poclbm_py2exe_20120205" poclbm.exe  MartyChubbs:password@mmpool.bitparking.com:15098 -d0 -v -w128
start "GPU2" /AFFINITY 1 /D"c:\poclbm_py2exe_20120205" poclbm.exe  MartyChubbs:password@mmpool.bitparking.com:15098 -d1 -v -w128
start "GPU3" /AFFINITY 1 /D"c:\poclbm_py2exe_20120205" poclbm.exe  MartyChubbs:password@mmpool.bitparking.com:15098 -d2 -v -w128

and save it as "mine.bat" not mine.bat.txt

double click mine.bat to start mining
