Cant debug in x++

Hello All,

   i have the 'Execute business operations in CIL' check box checked under the Tool/Options/Development but for some reason I don't see the debugger picking up the on the server or called from classes. It was debugging before I just had my DEV machine refreshed with the production copy and something got changed and doesn't debug it now. When I put the debugging break point in the forms't init method it does stop there but it doesn't do on the classes. We are using AX 20-12 R3 CU12. Am I missing something?
