Using Win 98, when I go to Settings, Add/remove programs, and select K-Meleon (remove only), I get the following error message:
"An error occurred while trying to uninstall K-Meleon(remove only). It may have allready been uninstalled."
But it's not uninstalled - it still runs. I imagine that K-Meleon puts files in the Windows system folder and perhaps other folders so just deleting the K-Meleon folder won't completely remove the program.
