[Xastir] What is it

[Murry]

I have installed Xastir-1.9.2 and have something unusual.If I click on 
Interface/interface control, iget what looks like a rocket waiting to be 
launched, or else it is a blue pencil standing on it's eraser. I also 
get it if I click on Help/help index or File/configure/timing, and some 
others.
Map chooser works OK, lets me load a map.
I use Linux Mint 4.0
Anyone know what this is or how to get rid of it, or use it.
