giofyxle ,
Sorry that you are seeing this issue.
Can you answer some more questions for me to understand the issue better?
1) Can you share your MyEclipse Build Id from Help > About MyEclipse Enterprise Edition > Build Id ? Paste the Build Id here.
2) Which version of TFS are you working with ? How did you install the TFS plugin? Is it using Pulse/Update Archive site? Can you recheck if the version of TFS plugin is compatible with base Eclipse version of MyEclipse ?
3) Do you see any errors of interest logged in the .log file which is located at <workspace>/.metadata/.log? If yes then paste them here for me.
4) Can you also attach a screenshot to help me get a visual of the problem ? Here is an FAQ on how to upload files to forums : https://www.genuitec.com/forums/topic/troubleshooting-how-to-upload-attachments-on-forum/
5) Can you check if you see the same issue when working on Classic Eclipse installation as MyEclipse is based on Eclipse IDE?
Let me know how this works for you.
