plugin deactivation deletes form

This happened to me to. Mae sure you run the backup forms feature in the settings before you deactivate the plugin. It stinks a pain to have to remember to do that but maybe this will be fix by the author in the next release,

Same here.. Forms get lost by deactivating, the captcha graphic won’t show. I hope the fix comes fast.

You can find the fix here: https://github.com/bgermann/cforms2/commit/d9dfa2ca87e7c620788479c7e46702ff1e9c02e6

Next version will contain it.
