Copy(paste) ''serialize'' error always occurs with task, never with components

Some more insight into the error I am getting.

It always occurs at the task (control flow) level and never at the component (data flow) level

It always occurs on the 'copy' action.

I have tried all the msxml/registry recommendations to no avail.

once again here are the error details

===================================

An error occurred while objects were being copied. SSIS Designer could not serialize the SSIS runtime objects. (Microsoft Visual Studio)

===================================

Could not copy object 'SQT Drop Create RAWMigDeal RAWBarrier table' to the clipboard.

At this point, if you've re-installed and this basic operation (clipboard cut/copy) continues to occur, I would see if you can get SSIS working in a VPC (virtual PC 2007 is a free download) with undo disks set to on, so you can just get back to a clean slate if need be.

Now, using the SSIS package xml provided, cut/copy and paste from a Windows Vista x64 OS work fine. There was not, nor has their ever been (on that machine) or any of the approximately 15 different SSIS installs (some Vista, some XP, some Win2k3, some 32 bit, some 64 bit, some VPC), that error. So, all that means the package xml is not the issue.

Now, looking at the dlls and assemblies being pulled in, the following below 2 are prominently used, which you've already re-registered.

msxml3.dll

msxml6.dll
