PL/SQL Developer hangs

[akuepfer]

PL/SQL Developer hangs when I do the following two actions:

Step with the debugger though a procedure of a PL/SQL Package

Switch to an other Window and compile a correctd version of this package without stopping the debugger

This will indeed cause a database locking situation. It will time out in 10 minutes. To prevent this, disable the "Allow compilation while running" preference (Tools > Preferences > Program Window).
