[Lazarus] Strange problem with Step Over (F8)
I'm having very strange problem, when debuging under Lazarus. When program is stopped and is on a method call line, then pressing F8 causes it to step into method call, instead of going to next line. Lazarus 1.2.4 32 bit, Windows 7 64 bit, 64 bit crosscompiling is installed, but I'm I'm compiling with build mode's all set to default. -- Virgo Pärna virgo.pa...@mail.ee -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

LazDaemon uses the same classes internally yet it does not work. Yes, it is strange. Now that I think of it, I actually did not use LazDaemon. It was brookframework daemon, that used TCustomDaemonApplication and TCustomDaemonMapper.
