Unable to Select Header when Modifying View

While working earlier today on a client server (Windows Server 2008 R2) in CRM4, I came across an incredibly annoying issue: I was unable to select a header in a view in order to move or delete it. It turns out, the client machine had IE Enhanced Security Configuration enabled, which was causing this very peculiar bug!

To disable IE ESC:

1) Open up the Server Manager.
2) On the bottom right of the Manager, under Security Information, click "Configure IE ESC".
3) Set both options to Off.

Now that these are disabled, you should be able to select your column headers!

Error Accessing CRM 2011 Online Plugin-Registration Tool

This can be a frustrating error when trying to access CRM 2011 Online via the plugin registration tool:

Luckily, there is a pretty simple fix. Open up your %userprofile%\LiveDeviceID\ folder, and delete LiveDevice.xml (back it up in case something goes wrong!).

Restart the plugin registration tool, and it should now connect properly!
