When he try to change the project (dropdown on the upper right), Mantis shows the list of availible projects and after selecting one project, Mantis switch allways back to one specific project ("xyz"). He can not change to any other project or to the "All Projects" view. He remains allways in the Project "xyz".
This error is comming only fith Firefox. With IE there is no problem

He is using like the others Firefox 1.5.0.7. We are working on Mantis 1.0.5.
All the other administrators have no problems.
Does any one of you know a solution?
bye
