Pressing "Continue" means "Continue within current module / event". So if you have accidentally left debugger on and go to open a memo, you have to press continue 10 times and lose a few hairs.
In any case, you might know when you want debugger to kick in (eg when you click a button), and not run through every module on form open.
A Sleep button would keep debugger, it would go to sleep until woken up by another "Wake" button on the debugger bar.
Hey I know someone in Lotus is probaby quietly writing a brand new debugger, but this would be a great (and hopefully easy) improvement.
