CHIRP

I am a new user and I appreciate the function of the Chirp program. I have some difficulty in removing an old version of the program to install the newer, which I find works better. I have found just uninstalling does not remove all of the files and I must search around to complete that process. And, after installing a new version, it seems to take a rather long time for the program to respond when I select it to load on the first usage. After that it loads quickly. Just wanted to let you know. Not complaining, just for your information.
Thanks for this tool!
