Hi Marco,
I have installed a Virtual Machine running XP mode (for Oracle Reports&Forms) and installed 10g on that as well. PL/SQL Developer runs fine there. Maybe the combination Win7 & 10g gives me the problems. I'll try to install 11g. Thanks.

Hi,
after installing 10g on Win7 i cannot get PL/SQL Developer to connect with Oracle. It is giving me:
ORA-12170: TNS:Connect timeout occurred
I am able to TNSPING to the database and SQL*Plus is also working.
In Preferences => Connection => Oracle Home is can select the Oracle home, but...
