A lot of shells cache the results of a PATH search so that they do not continually rescan all of the directories on the PATH looking for stuff. Most of the time this speeds stuff up nicely. But sometimes those caches become a pain. My solution, which I admit is extreme, is to restart the shell. So say I'm running ksh. I do this:
exec ksh
This causes the shell to replace itself with a new copy. ksh calls this particular feature "tracked aliases" and I think that "unalias gvim" would work, but I actually never have tried it. I just restart the whole shell.
