I use sotice 405.I have downloaded de latest debugger(winice.exe) from numega.It works.(I use windows me)
But when i set breakpoint getwindowtexta,then i can't get out from
softice(using ctrl+d,x or f5) appearing a
message like this: "break due to bpx user32!getwindowtexta".It only occurs
with getwindowtexta,not the others(like getwindowtextw).
what is happen?

uh...my guess would be that GetWindowTextA is executed. ;-)

Hit F11 & note the name of the process you land in....if it's not a system .dll, or the program you are debugging, close that program & try again (I have this problem with hmemcpy & running ANYTHING besides the app I'm working on.) :-)
