Apparently your termcap settings are causing this. Try this:
:set t_ti= t_ks=
But then something else might break...
It might have something to do with the colorscheme you are using, esp.

Q: What is the difference betwee open-source and commercial software?
A: If you have a problem with commercial software you can call a phone
number and they will tell you it might be solved in a future version.
For open-source software there isn't a phone number to call, but you
get the solution within a day.
