Automatically stops on non-breakpoint line

[FLabrecque]

I have a weird problem. When I click on my button to launch the event, it runs through some of the code. It then stops on the same line, without it being a breakpoint. This error seems to come and go. Any idea what the heck this is?

Just to clarify, this error happens 75% of the time (or at least the first time I launch the event). It always stops on the same line.
