This is a bug in version 1.4: see our news.

We have located and fixed the bug in Spybot - Search & Destroy 1.5; the problem does not exist there anymore, neither does it in any later version. So the best solution is to download and to install the up-to-date version: Spybot-S&D 1.6.0.

As a workaround for those who want to stick to version 1.4 you can work with your keyboard. Use the cursor keys to switch between the buttons (Allow is on the left, Deny on the right) and the space key to enter your selection. You can also press "A" on your keyboard for Allow change or "D" for Deny change. The Checkbox for Remember this decision will work correctly in spite of the graphical issue. If you do not like to use the above workarounds, you can disable TeaTimer as follows:

1. Go into the Advanced Mode of Spybot-S&D (via menu Mode)
2. Choose Tools, then Resident in the left navigation bar
3. Uncheck the following: Resident "TeaTimer" (Protection of over-all system settings) active.

For more information please have a look at our forum here, or at the workaround here.
