Hi,
When using the debugger in pgAdmin on Windows 8 debugging any pl/pgsql funtion it hangs and the pgAdmin should be close from the task manager.
This only happens on whatever version of pgAdmin used on Windows 8 64 bits (for example pgAdmin 1.18.0).
To reproduce the problem try to debug a pl/pgsql function and after the debug window shows, try to close the debug window and you will see that the pgAdmin hangs and it should be restarted.
Thank you in advance.
