The data is the square brackets are performance stats. Time taken between break-points. Can be switch off on the vMicro debugger menu.

Your post shows two debug notifications 
1) a trace message 
2) a break/pause message telling you the debugger is waiting for your instruction to continue. It confirms the breakpoint info.

Did you mean to make a debug upload?

If you click the Continue Execution checkbox on the breakpoint properties then you would only see one message.

If you do not add your own breakpoint message but allow breakpoint pause then you would only see one message.

If we didn't add the breakpoint source to the pause message you would not know for sure where the pause is, this is especially the case when working with more than one breakpoint.

A possible future enhancement might be to continue to show the pause line number but exclude the source code if the last debug message is for the same breakpoint and if users have added a message that includes the source code.

You don't need to add any message in the breakpoint message other than the {variables}. Then you would see values in the message and watch expressions + source code in the pause message.

It seems like things are working okay considering all the possible variations. Altering your message might remove the confusion for you?

Great. 

fyi: Yes also do not need the comma between the {variables} but it might be easier for you. The watch expressions window should show the values + min/max clearly along with which breakpoint they apply too.

Thanks for the note we will look at that however it might be a vs bug. Did you see the watch expressions is a dockable window? Can be useful when viewing long expressions. There is also a "word wrap" mini icon on the trace window that will wrap the trace text.
