First of all, to the publisher, thank you very much for this program, love it.
I'm running Windows 7 Ultimate 64 bit SP1. My suggested problem/resolution is related to the Taskbar Re-emerging (I have no idea if this is related to the same problem the current reader is having). I hope the following helps others in trying to get Taskbar Eliminator to work. By the way I am using the free version.
I had set Taskbar Eliminator to start with Windows. When I logged into Windows, Taskbar Eliminator worked but only initially - after 40 seconds, the taskbar ALWAYS re-emerged. So I started making notes as to the exact time (based on my system time) that the taskbar re-emerged. I then cross referenced this time with the events in my system event log (I used a filter based on the time I had noted, see image below):
( I can't post the image because im a guest on this forum but here is the link anyway (replace hashes with forward slashes - http:##tinypic.com#view.php?pic=14jm78w&s=6 )
This led me to see that the following event was happening at the same time the taskbar was re-emerging:
0000000027: 2013-03-06 21:18:51:653 Exception <UpdateJumpLists>: A valid active Window is needed to update the Taskbar
Exception Called by: ATI.ACE.CLI.Component.Dashboard.DBFavouritesSectionVMController::DoSetTree processID:04464 threadID:(CCCThreadNew:Dashboard) domainName:(CCC.exe ) assemblyName:(CLI.Component.Dashboard, Version=188.8.131.52, Culture=neutral, PublicKeyToken=90ba9c70f846762e)
Notice the mention of the taskbar … obviously something is happening here that related to the very thing I was trying to get working. For the unknowing, CCC.exe is ATI's Catalyst Control Center (the Graphics Control Panel for ATI Graphics Cards). So after I found this out, I went into msconfig and disabled CCC.exe as a start up program. From then on, and a few restarts later and counting, I haven't had a problem with Taskbar Eliminator since.
I am not saying that CCC.exe is causing the problem for everyone, but I am saying that you might be able to find out what is causing your taskbar to re-appear using the method that I used.
Anyway, I thought i'd contribute. Thanks. If I have helped you then please post and say thanks so I can see how many i've helped! :)
