[help] Y'z dock icon messing

can you help me to solve my issue?

an icons at dock are too close to each other... see sshot.

No setting found for set interval or something like this...

hmmm...what size icons are you using?

mmm... not sure

i think i set large icon but i don't use any 3-rd part apps to set icon size. only standart WinXP settings.
