Hello. I have master page that is shown as checked out in sharepoint designer. Yes, because I choose to check it out and edit in Sharepoint Designer. Unfortunately sharepoint Designer says that I am not allowed to check out/ check in / or save this file. Apparently SharePoint designer does not realize I am the same user as Designer seems to use my windows account (wich cannot be used with sharepoint).
Second problem. I used SharePoint to check my master page in. Unfortanately SharePoint Designer says that it still checked out.
