KB00013 - Where can I download an older version of Stickies?

Answer: from this page

Click here to download the installer for v4.5b (528k)

Click here to download the installer for v5.2b (598k)

Click here to download the installer for v6.7a (788k)

Click here to download the installer for v7.1e (1052k)

Click here to download the installer for v8.0c (1604k)

Click here to download the installer for v9.0e (1642k)

Each of these are the final, and therefore most bug-free and feature-rich, versions of v4 - v9 of Stickies.

Unless you have a good reason for using older code, I'd recommend that you use the most recent release of the app. More recent versions are more likely to have fewer bugs, will certainly have more features, and the moves to first v8 and then v10 mean data is written in an improved and safer manner.
