When i set a breakpoint on soft that opens new window

like Crack me that has Button you click th button then you got another
Dialog then you need to write the serial number
like this one: http://biw.rult.at/tuts/crue2tut.zip ("http://biw.rult.at/tuts/crue2tut.zip")

ok when ANY debbugger that i use Breaks on GetDlgItemTextA
it breaks and not responding and it happens on any debbuger that im trying to use (OS:xp so didnt try SI)

Do you have Any Keyloggers?Any programs that attach to a new program?
had the same problem but turns out it was aprog called ghost keylogger

whats the problem its working nice its a simple repecmpsb
launches a dilaog box and closes it then hashes the serial with a harcoded
string and repecmpsb with a hardcoded hash
btw the first Letter is R and even Entering just one Letter as password you can pass the test its working fine
doesnt block nothing
works fine on windbg as well
check your pc if you find any freeze for some malwares or some such crap

or check if you are breakpointing on messageloop
if you have set a break point on message loop it might be breaking
a lot of times and you should be thinking ollydbg is freezing
