Render Suddenly Changes

Hello,

Something incredible has happened! Okay, well I'll post the steps up, but this seems to be extremely hard to replicate as far as I tried several times.

Steps that I remember doing:

1. Start rendering some picture using filter forge stand alone.
2. Randomly click on the filter library (or click specifically on the filter library, and blindly choose any filter.)
3. The settings change, and the filter changes. The render resets starting again but with the selected filter.

So in other words, the program, which is supposed to be locked and unusable... did not seem to be locked when something happened.

I attached a supporting screenshot in hopes this would clarify what I mean.

Thanks!
