I worked through the steps and still had problems with the "ghost" controls. However, when I simply removed the TeeTree package then this solved the issue. So, not sure if all of the steps are necessary or whether the issue is related just to the TeeTree package.

Any new insights into the ghost control issue? Is there a fix/workaround available yet?

Yes, I have used the Recompile tool to rebuild and install the latest source (from November 2011 I think) with Update 4.

When I remove the TeeChartPro packages both the "ghost" controls and Access Violations are gone.

Me too...

I am running XE2 Update 4 on Win7 64bit.

In addition to not showing the visual controls, I see Access Violation errors in fmx162.bpl when clicking on the non-visual controls, such as a TStyleBook.

These problems are gone when I remove the TChartPro packages.
