Hi guys
am getting unhandled exception when scrolling thru objects in object explorer in sql server management studio. it happens intermittently when i click different objects like diagrams,tables etc.,
any help on this much appreciated.
BTW previously i had RC1 but now i have standard edition.i used get similar error with RC1 also.

the error i get is
"Unhandled exception has occured in a component in your application.if you click continue, the application
will ignore this error and attempt to continue.

InvalidArgument=Value of '6' is not valid for 'index'.
parameter name : Index"

following is actual log details
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging

For example:

When JIT debugging is enabled, any unhandled exception
