Shortcut Entries Lock-up

I bought Object Dock Plus a couple days ago and can't seem to be able to use an entry to access any of my internet based programs.  I have Firefox and a couple MMO's.  They start fine, but 5-10 seconds in they just lock up and I have to use the Task Manager to close them.  They work just fine when I access them though the Start Menu or personally activate the .exe file.  I've made these types of adjustments before with a Vista version of Mac's RocketLauncher and that worked great, so what am I doing wrong? (Example:I used this Link - "C:\Program Files\Mozilla Firefox\firefox.exe," this for the Arguments - "http://my.yahoo.com/,"  and this for the field Start In - "C:\Program Files\Mozilla Firefox" for my browser.  I made/edited all my entries by copying the location and .exe file and pasting it to the links.  Would anyone give me a hand and explain what I need to do to fix this?  I'm using Vista 32bit OS, 2.1Ghz, 3gig Ram, OD+ v1.9 b535u w/ 1 Tab & 1 Zoom Dock.  Any help is much appreciated.
