I am using olldbg 2.0.1h and loaded a dll into it, but during the loading it shows me that:

Debugged application has modified the debugging registers. Maybe it called ZwContinue() or SetDebugContext(). The modifications are saved to the log.

And from the log:


77C1F2A1 Modified debug registers of main thread
DR2: old 7C90D05E, new 00000000
DR3: old 004100CA, new 00000000
DR7: old 00002150, new 00000000


So what does this mean and how to deal with it?
