I used to have a Clickstand, and it had its uses, but I lost it, and never really missed it enough to replace it. The thing that came with the Clickstand that I continue to use is the elastic bands that you use to "lock" the brakes, so the bike doesn't roll away from the stand. Those are really handy for leaning the bike on something and not having it roll.

So, yeah, just a little bit of something to hold your brake lever down may solve all of your problems.
