Problem with returning to bash from another program

[Cameron Pulsford]

I am running bash 4.0.10 (installed through macports)
hw = Macbook 2,1 os = mac os x 10.5.6
Compiled with gcc 4.0.1

A lot of times after a long vim session when I return to bash, my  
cursor is not on a new line, it's on a previous line and it seems like  
bash is in overtype mode. So whatever I type is getting replaced over  
what was already on that line, but when I press enter the command gets  
executed normally. So even though it might look like "gcaudoku.py",  
the command that actually gets executed when I press enter is just  
"gca" (an alias of mine). Whenever I try to reproduce this I can't,  
but it happens to me a few times a day, and the only thing that ever  
triggers it is exiting vim. Attached is a picture of the problem. (I  
unfortunately pressed backspace which cleared what was written on the  
line before so this doesn't illustrate the overtype behavior, but it  
is still clear the my cursor is not on the newest line)
