Casanunda - you're welcome. Thanks for the banana.
I've investigated the slider problem that Marcin mentioned, and have released version 3.2 to fix it. This new release includes the following changes to the slider timer:
1. The slider will no longer be able to move past its boundaries. This bug is reproducible in the 3.1 (and earlier) slider timer by moving the slider to either end, then clicking around on the bar. Not a serious problem, but you can download version 3.2 for a fix.
2. It is now easier to move the timer window. You can now click and hold on any of the four edges, as well as any space between the timers, to get the move cursor.
3. In addition to dragging the slider, there are now two other options for moving the slider. You can click on the bar to either side of the slider to move it in large increments, or you can use the buttons (full version only) to move it in small increments.
