Mouse and trim sensibility problem.

Hi guys,I just installed 2004 and I'm having a great time, the only problem I have so far is the mouse click sensibility, for example when I click on the VOR to adjust it every click sends the needle flying like 10 or 15 degrees! I can't fine tune it like I use to do with 2002 where every click would be one degree, I have the same problem with trim while using my CH Products yoke, every time I press the "trim" it moves way too much.Can anyone help? thank you so much for your time :)Alex.
