This has been an insane issue for years. When you adjust the columns in the Component Inspector window, then try to adjust a parameter, the inspector scrolls you like 200 pixels out to the right in the panel, and you can't see the content in the parameter field, rendering it mostly useless. The only way to get it to behave that I know of at this point woudl be to reboot Flash. This is ridiculous. Does anyone know of any solutions? Screenshot attached.
