user interface issues

The width of the combo boxes for certain areas are too small and categories with longer names are cut off - for example in the case of the drop down list and the pop up window for categories of assets.See screenshot 1 and screenshot 2

Also the field Product in the Asset Details looks weird for categories with names longer than 19 characters.See screenshot 3

Please help me in this problem. It`s impossible to select de categories with large names from de combobox and i don`t intend to cut off names for this reason.

P.S I noticed that exist 2 files related to combox settings in \AdventNet\ME\ServiceDesk\applications\extracted\AdventNetServiceDesk.eear\AdventNetServiceDeskWC.ear\AdventNetServiceDesk.war\scripts\ :

combo.css and combobox.js
I made changes in combo.css but no results.
