"Toggle" and "forget" application buttons do not work sometimes (and sometimes "forget" works as "toggle")

[positron96]

I have rooted LG P500 (Android 2.3.3), latest superuser from market.

When viewing application details in superuser there are buttons "toggle" and "forget" at the bottom of screen.

The problem is:
When viewing application that is in blacklist, theese buttons do not work (do not trigger visual blink or whatever at all).
When viewing a whitelisted application, "forget" button sometimes works as "toggle", meaning app is moved to blacklist and cannot be forgotten after that.

All in all, on LG P500 Superuser is very buggy and crashes a lot.
