I get a run-time error '0' when i go to System Tab / Company/ Package Settings - then click on the AR setup

I get the same exact error message when going to System Tab / Company/ Package Settings/ Order Entry setup - then i click on the 'Default Accounts' Tab.

Any ideas?

Do you have 2 monitors? If so try opening the screen from both monitors and make sure you are getting the same error in both cases.

I do use two monitors, however i am also functioning in a terminal server environment. I log into terminal server to access my Macola, therefore my 2nd monitor is dedicated to my local machine. Do you think that would still have an impact with this??

Possibly. Go to a directly connected machine (not using terminal services) and try the same menu option, logged in with the same user you are now. If you don't get an error then this is related to terminal services. Please post your findings and we'll take it from here.
