Exactly
I am having the same issue....When I click on the shaders tab...it is blank. When I right click in the left window and select tabs and then select reset default directory..They pop right up. Give it a try and see if this works for you. I have to do this everytime I start MAYA 4.5.
Thanks for the response,
