>Thanks - it's just single stepping and comparing the changes on both debuggers Something like ALT Tab + F6 +ALT Tab + F6 and then looking into the locals window. The issue is, that the vars are not on the same place, so if one found it on the first, one still has to search the other. The pattern is different and that slows down a lot.

If everything else fails, you may end up putting the variables you want in the watch window.
