MATE - lost icons - strange panel end - themes

[Vito49]

Hello, I tried MATE and of course I tried to configure it the way I like ... and these are the problems I encountered and didn't find an answer for:

1) installing themes gives an error (please see viewtopic.php?f=206&t=92321)
2) both panels have a strange triangle on the right end, it covers almost the whole icon located there
3) I lost the volume and update icons in the task-bar, no way to get them back

Sorry for bothering you and certainly sorry for my bad English.

2)make or edit the file in your home folder
gedit .gtkrc-2.0

should look like this after edit:

style "default-style"
{
GtkWindow::resize-grip-height = 0
GtkWindow::resize-grip-width = 0
}

class "GtkWidget" style "default-style"

or use the latest mate tridex repo to have this allready fixed:

3) it should be indicator applet i think
right click on panel , add applets and find the indicator applet and add
