Whenever I select and object to modify the tabs are hiding automatically. I then have to cycle through panel buttons to find the one I want. Is this normal? Is there a way to change this? Thanks
After the last tab, normally modify there is a pulldown button a small triangle. Select the small triangle on the right of the icon, and make sure 'Cycle through all'.
If the panels aren't visible press the triangle in the box to cycle through the choices.
Hope this helps.

It sounds like you might be seeing an issue that is related to .NET 4.5. If you have .NET 4.5 installed you will need to make sure and update your Revit installation with the most recent update. That will clar up the compatibility issues between .NET 4.5 and Revit.
Note: If you are not running Revit 2013 this will not work. Older versions of Revit (2012 and older) are NOT compatible with .NET 4.5 and there is not an update currently avaliable for older versions of Revit. In this case the .NET version will need to be rolled back to .NET 4.0 (I think that is the previous release.)
