Filetab is missing when switching through new created workspaces

[Thosti]

Hello,

I have created two new workspace by copying settings (menues and toolbars) from AutoCAD Standard workspace. Here are some codesnipes

                Workspace baseWorkspace = cs.getWorkspace(WSNAMEBaseWorkspace);                

                Workspace newWS = new Workspace(cs, newWSName);

                foreach (WorkspacePopMenu currPopMenu in baseWorkspace.WorkspacePopMenus)
                    newWS.WorkspacePopMenus.Add(currPopMenu);

                foreach (WorkspaceToolbar currToolbar in baseWorkspace.WorkspaceToolbars)
                    newWS.WorkspaceToolbars.Add(currToolbar);  

                newWS.WorkspaceQuickAccessToolbar = baseWorkspace.WorkspaceQuickAccessToolbar.Clone();

                newWS.MenuBar = MenuBarToggle.on;    

                retVal = true;            

 then I save the modified cui

if (cs.IsModified)
                cs.Save();

            for (int i = 0; i < numPartialFiles; i++)
            {
                if (partials[i].IsModified)
                    partials[i].Save();
            }
            
            Application.ReloadAllMenus();

 and set the new created workspace as current workspace (Application.SetSystemVariable("WSCURRENT", wsname);)

The code seems to work except for the filetab. When switching thorugh workspaces with no ribbon in the workspace-control-window filetab looses state and isn't displayed. Switching to a ribbon workspace and back to any classic workspace filetab is continuous displayed.

My workaround at the moment is to SendStringToExecute _FILETABCLOSE and after that _FILETAB.

I have noticed that there is a palette under options->workspaces called filetab. This palette is that to display true.

I'm open to suggestions?

Have a nice day
