Team Coding and SourceSafe not working in 11.6

I am just starting to look at 11.6, and have run into serious problems with
Team Coding and SourceSafe.

(1) When I open a package protected by Team coding, I get a "Select
Project" popup. I search for and select the appropriate package, select it,
and get this error message: "Access violation at address 0043F520 in module
'Toad.exe'. Read of address 98E225AF"

I try it again, this time I cancel the popup. That results in this error:
"Unable to get revision information for D:\SourceSafe Working Folder\SBT
\Report Server\SBTPLUS\Stored Procedures\SBTPLUS.CR_MISC_RPTS.PKB from VCS
repository."

That file path is the working directory as set in Team Coding, and yes, the
VCS Project is  correctly set there as well.

(2) I selected another package that happened to be checked out by someone
else. The package opened without error, but it wasn't locked. Toad seemed
to think that I had it checked out instead of someone else.

(3) Views - I simply click on a view name in the Schema Browser, then I get
"Toad for Oracle has encountered a problem. We are sorry ... Either you do
not have sufficient privileges to access this object, or it does not
exist."

I click OK and Toad restarts.

If I disable Team Coding, these problems go away. I can go back to 11.5 and
all works well.

I'll mention one thing. I have no reason to think there is a connection,
but I'll raise it anyway just in case. One of the fixes made to this
version is "Code Control window does not populate" (ID 102,090). I had this
problem, and really appreciate the fix because I had to keep version 10.6
around just to edit Code Collections.

So now I can view the Code Collections, but I can't open anything under its
control.
