Since my laptop screen has a very high resolution (1400x1050) i have to set the screen properties to 120DPI
to be able to read what's on the screen, otherwise the fonts are just too small

I am using windows XP. You can set the DPI here:
Display properties, settings, advanced, general, DPI setting..
If you set the display to 120DPI you will notice that the input text doesn't fit in the boxes anymore.
I kind of 'solved' the problem by resizing both 'bluelight.gif' and 'bluelight2.jpg' (make them about 25% bigger)
Can Keybreeze take this 'bug' into account in the next release of Keybreeze?
Btw. I just started to use your program and it looks very handy. Good work!
